1.Nature Catalysis: Pt monoatomic Mxene catalyst is used to greatly improve the performance of electrocatalytic hydrogen evolution

So far, Pt is considered to be one of the most active HER catalytic materials, while monoatomic Pt catalysts have shown lower cost and superior activity. How to prepare excellent monoatomic Pt catalysts to achieve higher activity HER performance is a key issue in the fields of catalysis and energy research. Professor Wang Guoxiu‘s team, Yury Gogotsi‘s team at Drexel University, and Li Yadong and Chen Chen‘s team at Tsinghua University jointly published a study entitled "Single platinum atoms immobilized on an MXene as an efficient catalyst for the hydrogen evolution reaction" on Nature Catalysis. In the thesis, a strategy for electrochemical in situ synthesis of MXene-supported monoatomic Pt catalysts was proposed, and at the same time, efficient hydrogen production performance was achieved. The article points out that during the electrochemical stripping of MXene in an acidic system, H + interacts with the Mo-O bond on the surface of MXene, on the one hand, it can efficiently produce hydrogen and promote the stripping to obtain nanosheets. On the other hand, the bond between H + and Mo-O generates Mo-OH2 groups, forms Mo vacancies, and finally obtains Mo2TiC2Tx-Pt single-atom catalyst. In summary, studies show that H + in acidic systems promotes the formation of electrochemically stripped MXene nanosheets and the synthesis of monoatomic Pt-supported catalysts.

2.Nature Communications: Stable room temperature sodium-sulfur battery

High-temperature sodium-sulfur batteries operating at 300-350 ° C have been commercialized for large-scale energy storage and conversion. However, security issues have greatly inhibited their widespread adoption. To this end, Professor Wang Guoxiu‘s team and the team of Professor Li Baohua of Tsinghua University and the team of Professor Michel Armand of the CIC ENERGIGUNE Institute in Spain jointly published a title entitled "A room-temperature sodium-sulfur battery with high capacity and stable cycling performance" on Nature Communications. The research paper reports a high-performance room temperature sodium-sulfur battery using a "cocktail-optimized" electrolyte system. The electrolyte uses propylene carbonate and fluoroethylene carbonate as co-solvents, and high-concentration sodium salt and indium iodide as additives. First-principles calculations and experimental characterizations confirm that fluoroethylene carbonate solvents and high salt concentrations not only greatly reduce the solubility of sodium polysulfides, but also build a solid solid polymer electrolyte (SEI) on the sodium anode during cycling. membrane. Indium iodide as a redox medium not only increases the kinetic conversion of sodium sulfide on the positive electrode, but also forms an indium passivation layer on the negative electrode to prevent it from being corroded by sodium polysulfide. The sodium-sulfur battery has high capacity and long-cycle stability, and provides a new way for the development of low-cost and high-performance room-temperature sodium-sulfur batteries.

3.Nature Communications: Multifunctional functionalized ionic liquid used to improve lithium-oxygen battery solution mediation

The large overpotential of a lithium-oxygen battery during a charge-discharge cycle results in the formation of by-products and a short cycle life. Professor Wang Guoxiu‘s team and the Peng Zhangquan team of the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences and the team of Professor Michel Armand of the CICENERGIGUNE Institute of Spain jointly published a study entitled "A versatile functionalized ionic liquid to comprehensively boost the solution-mediated performances of lithium-oxygen batteries" on Nature Communications. Thesis, with a redox-active 2,2,6,6-tetramethyl-1-piperidinyloxy moiety, a multifunctional TEMPO grafted ionic liquid (IL-TEMPO), with a redox mediator, oxygen Various functions of shuttle, lithium metal protective additive and electrolyte solvent. Among them, n- / p-doping makes IL-TEMPO play the role of redox mediator and oxygen shuttle. Compared with the pure ether-based electrolyte, the discharge capacity is increased by 33 times, and the overpotential is reduced to an extremely low value of 0.9V. The ionic liquid also forms a stable SEI to suppress side reactions and ensure smooth lithium stripping / plating. The proportion of ionic liquid in the electrolyte affects the reaction mechanism. At high concentrations, amorphous Li2O2 is formed as a discharge product, resulting in a long cycle life (> 200 cycles). In addition, the unique properties of IL-TEMPO enable the battery to have excellent electrochemical performance in harsh environments, such as at a high temperature of 70 ° C or in an air atmosphere.

4.Advanced Materials: Application of a non-dendritic metal sodium anode in high energy density batteries

Professor Wang Guoxiu‘s team collaborated with Professor Wang Dan of the Institute of Process Engineering of the Chinese Academy of Sciences to jointly publish a research paper entitled "Dendrite-free sodium-metal anodes for high-energy sodium-metal batteries" on Advanced Materials, and proposed a metal-inhibitory A New Strategy for Sodium Negative Dendritic Growth. Sodium metal is one of the most promising electrode materials for the next generation of low-cost rechargeable batteries. However, safety issues caused by the dendrite growth of the sodium metal negative electrode limit the practical application of rechargeable sodium metal batteries. In this paper, paper made from nitrogen and sulfur co-doped carbon nanotubes (NSCNT) was used to control sodium nucleation behavior and inhibit sodium dendrite growth. The functional groups containing nitrogen and sulfur on the carbon nanotubes make the NSCNT paper highly "sodium-philic", which can regulate the initial sodium nucleation behavior and guide the uniform distribution of sodium on the NSCNT paper. The experimental results show that the metal sodium / NSCNT paper composite negative electrode exhibits no dendritic morphology and excellent cycle stability during repeated sodium deposition and peeling processes. The cycle stability of the sodium / oxygen battery using the composite negative electrode is significantly improved. This work opens a new path for the development of the next generation of high-energy-density sodium metal batteries.

9.Journal of the American Chemical Society: Limited to Mxene (Ti3C2) vacant monoatomic catalysts for efficient functional catalysis of carbon dioxide

A central issue in monoatomic catalysis is the establishment of strong interactions between single atoms and stable support. Chen Chen‘s team from Tsinghua University and Professor Wang Guoxiu‘s team published a research paper entitled "MXene (Ti3C2) Vacancy Confined Single-Atom Catalyst for Efficient Functionalization of CO2" in the Journal of the American Chemical Society. They reported on the use of ultra-thin The two-dimensional Ti3-xC2Ty MXene nanosheets are stable monoatomic catalysts prepared by a self-reduction stabilization method, which is characterized by rich Ti defect vacancy defects and high reduction ability. The single atom in it forms a strong metal-carbon bond with the Ti3-xC2Ty support and stabilizes it in the position previously occupied by Ti. The Pt-based monoatomic catalyst Pt1 / Ti3-xC2Ty provides a green way to consume greenhouse gas CO2 through the formylation of amines as the C1 source in organic synthesis. DFT calculations show that compared to Pt nanoparticles, a single Pt atom on Ti3-xC2Ty supports partial positive charge and atomic dispersion, which helps to significantly reduce the adsorption and activation energy of silane, CO2, and aniline, thereby improving catalytic performance .

11.Chem: Graphite-phase carbon nitride nanosheets as metal-free photocatalyst

Compared with traditional technologies such as ultraviolet disinfection, chlorination disinfection and ozone disinfection, water purification using solar photocatalytic disinfection is undoubtedly more energy-saving, economical and environmentally friendly, and it is expected to significantly alleviate the international problem of shortage of clean water. Professor Wang Guoxiu‘s team and Professor Wang Yi‘s team of Yangzhou University and Wang Dan‘s researcher team at the Chinese Academy of Sciences jointly published a research paper entitled "Edge-Functionalized g-C3N4 Nanosheets as a Highly Efficient Metal-free Photocatalyst for Safe Drinking Water" A non-metallic catalyst, a graphitic carbon nitride (g-C3N4) nanosheet modified with a fixed-point modification, was reported.

13.Nano Energy: Simple in situ film formation inhibits sodium anode growth

High-capacity sodium metal anodes provide new opportunities for developing the next generation of rechargeable batteries with high power and high energy density. However, many challenges still plague sodium metal batteries, including lower coulomb efficiency and sodium dendrites generated after repeated charge and discharge, which causes safety issues. In particular, compared with lithium metal anodes, sodium metal anodes have lower stability in organic electrolyte (such as carbonates) systems and are prone to the formation of sodium dendrites.

15.Advanced Functional Materials Overview: Status, Challenges and Prospects of Li2S Cathode and Its Ultra High Performance Lithium-Sulfur Battery

As a new-generation rechargeable battery system with high energy density and low cost, lithium-sulfur (Li-S) batteries have attracted increasing interest. If the problem of polysulfide shuttle effect is solved, lithium-sulfur batteries will realize their theoretical potential. Therefore, great efforts have been made to overcome this problem in terms of the physical limitations and chemisorption of polysulfides. Recently, it was found that replacing sulfur cathodes with lithium sulfide (Li2S) can not only largely avoid volume expansion problems during cycling, but also work with anode materials other than lithium metal to eliminate the seriousness of traditional Li-S batteries safe question. However, because Li2S-based cathode materials are sensitive to humidity and pre-lithiation of non-Li metal anode materials is often required in practical applications, developing practical Li-free metal Li-S battery systems faces many challenges. Professor Wang Guoxiu‘s team published a review paper entitled "Toward High Performance Lithium-Sulfur Batteries Based on Li2S Cathodes and Beyond: Status, Challenges, and Perspectives" in Advanced Functional Materials, reviewing the latest progress of Li-S batteries based on Li2S cathodes. It features improved safety, high coulomb efficiency and high energy density. The electrode activation process was also discussed, which is critical to achieving high performance. Extensive efforts are expected to bring breakthroughs to the development of Li2S cathode-based Li-S batteries.

16. Overview of Advanced Energy Materials: Improved metal compounds (MOFs, -S, -OH, -N, -C) as anode materials for Li-S batteries

Lithium-sulfur (Li-S) batteries have the same high-efficiency and extensive potential as lithium-ion (Li-ion) batteries, because sulfur electrodes have high theoretical capacity (1672 mA h g-1) and are affordable. However, commercialization of Li-S batteries is difficult to achieve. The shuttle effect of polysulfides inevitably leads to capacity decay. At present, people mostly solve this problem through physical limitation and chemical adsorption of polysulfides. Due to weak intermolecular interactions, physical confinement strategies do not work during long-term battery cycling. Chemisorption originates from polar interactions, Lewis acid-base interactions and sulfur chain connections significantly inhibit the shuttle effect of polysulfides. Researchers also found that metal compounds have strong chemical interactions with polysulfides. Professor Wang Guoxiu‘s team published a review paper entitled "Updated Metal Compounds (MOFs, -S, -OH, -N, -C) Used as Cathode Materials for Lithium-Sulfur Batteries" in Advanced Energy Materials, focusing on metal organic framework Sulfides, metal hydroxides, metal nitrides, metal carbides, and discusses how chemical interactions can be combined with the unique properties of these metal compounds to solve the problem of polysulfide shuttle effects.
