Abstract:
As a new type of topological magnet, TbMn6Sn6 has a planar Mn kagome lattice with out-of-plane magnetic moments. Previous studies have found spin-polarized Chern gapped Dirac fermions in TbMn6Sn6, which are advantageous to topological catalysis. In this study, we theoretically demonstrate that the TbMn6Sn6 (001) surface is favorable for CO2 reduction. The stability of different surface types is investigated, and then the reaction paths of CO2 reduction on the surfaces are revealed to prove that the product is selective. This work reveals the effect of magnetic topological materials on CO2 reduction.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
