Nitrogen-doped carbon-cobalt single-atom catalyst

Product Name

Chinese Name: Nitrogen-Doped Carbon Cobalt Single-Atom Catalyst

English Name: Co-N-C SAC

Product Overview

Single-atom catalysts refer to a type of catalyst in which isolated single atoms are uniformly dispersed on a support, with no interaction of any form between the individual atoms. In single-atom catalysts, the active metal is uniformly dispersed on the support in the form of single atoms, forming a unique coordination environment with the surrounding atoms.Common types of single-atom catalysts include noble metals such as Pt, Pd, Au, Ir, Ag, Rh, and non-noble metals such as Fe, Co, Ni, and Cu. Common supports include metals and metal oxides, such as Fe2O3, TiO2, and Al2O3, as well as carbon-based supports, such as carbon nanospheres, carbon nanofibers, graphene, metal-organic framework-derived carbon, covalent triazine framework, carbon nitride, and phthalocyanine-derived carbon.Preparation methods include high-temperature pyrolysis, impregnation, atomic layer deposition, metal-organic framework-derived methods, and electrochemical deposition. The single-atom catalysts provided by Northern University are obtained by high-temperature pyrolysis of nitrogen-containing carbon organics (such as PVP), resulting in an amorphous nitrogen-doped carbon support, with metal atoms derived from nitrate or chloride precursors.
