Abstract:
CO2 utilization is one of the hottest research topics worldwide. As a class of newly emerging and promising catalysts for electrochemical CO2 reduction (ECR) reaction, heteroatom-doped metal-Nx -C single atom catalysts (M-Nx -C SACs) attract extensive attentions. Nowadays, great progress, including structure modulation, identification of local coordination environment and ECR mechanism via advanced synthetic strategies, characterization techniques and theoretical calculations, have been achieved over heteroatom doped asymmetric M-Nx -C SACs, which boost the ECR performances and deepen the understanding of ECR mechanism. In this context, we summarize recent progresses in heteroatom-doped asymmetric M-Nx -C SACs, with emphasis on synthetic strategies and their applications in ECR reaction, along with current understanding on the ECR mechanisms both experimentally and theoretically. Finally, the challenges and perspectives for the heteroatom-doped asymmetric M-Nx -C SACs towards ECR are proposed.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
