MXene, a two-dimensional transition metal carbide/nitride, is currently receiving widespread attention. This is because the structure and element composition of MXene can be adjusted, and it exhibits a wide range of properties in applications such as (electro) catalysis. MXene has rich structural changes, high specific surface area, and high laboratory-level catalytic performance. It can be used as a better substrate material in a variety of heterogeneous catalytic and electrocatalytic reactions.

In view of this, the University of Barcelona Francesc Illas et al. reviewed the research progress of MXene materials as a replacement for traditional Pt-based catalysts for catalytic reactions.

Highlights of this article

Point 1. The interaction between metal and carbon and the influence of different end groups on the surface of MXene materials on the catalytic performance are discussed. In addition, the author summarizes the connection between MXene material simulation and experiment, and discusses the synthesis method and how to Discuss on scale. By combining with computational chemistry simulation model, the MXene material achieves high-efficiency catalysis is summarized.

Key point 2. MXene heterogeneous catalytic reaction: CO oxidation, CO2 activation/conversion, water gas reforming, nitrogen fixation, direct dehydrogenation/hydroxide; MXene electrocatalysis: HER, CO2 reduction, N2 reduction, OER/ORR. The development prospects of MXene catalysis: From the perspective of experimental technology, expand traditional MXene synthesis methods, such as synthesis from new structures of Si-, Zn-, Ga-MAX, and Lewis acid etching and other methods to treat MXene interface, which may be in the field of catalysis Make an impact and promote the development of catalysts. The current understanding of MXene catalysts is quite flawed, and there is still no good progress in large-scale industrial synthesis.
