Progress, Advantages, and Challenges of Topological Material Catalysts

Topological materials is one of the hottest topics in condensed matter physics because of its exotic properties such as robust metallic boundary states, Fermi arcs, and the spin-momentum-locking helicity. The topologically protected conducting boundary states spanning the whole bandgap are expected to serve as robust and wide-range-energy transition states facilitating catalytic reactions. Recently, some topological materials have been found to be high-performance catalysts, which might open an emerging research field. Herein, an overview of topological materials is given and then recent progress in topological material catalysts (TMCs) is presented. As it is a new field, more detailed and accurate mechanisms behind the high performance of TMCs are urgently needed. Combining theoretical and experimental studies is a promising way to resolve these puzzles. Heterostructures, dopants, and defects have the chance to tune the catalytic activity of TMCs while retaining topological surface states (TSSs). Also, more TMCs are needed to be discovered, and more catalytic reactions are to be investigated for TMCs in the future.

Automated summary

Topological materials with exotic properties such as stable boundary states and spin-momentum-locking helicity have potential applications in catalytic reactions. Recent discoveries of high-performance catalysts among topological materials have opened up a new research field. Combining theoretical and experimental studies is necessary to understand the mechanisms behind the high performance of topological material catalysts (TMCs). In addition, heterostructures, dopants, and defects can be used to tune the catalytic activity of TMCs while retaining topological surface states.
