The electrocatalytic reduction of CO2 (CO2RR) to high market value HCOOH is highly attractive and challenging in chemistry. p-Block metals (Sn, Bi, In, Pb, Sb) are promising candidates trigger formate due their specific stabilization the HCOO* intermediate, while overpotential low selectivity have now limited its practical application. Herein, we rationally designed a series p-block single atom anchored MoS2 monolayer catalysts for efficient electroreduction by DFT methods. systematic thermal evaluation demonstrates that Sn, Sb, Tl, Bi atoms could be atomically dispersed on 1T-MoS2 with stability potentially synthesized experiment. We reveal catalytic CO2RR activity metal correlated degree charge transfer between substrate, higher distribution induced stronger interaction HCOO intermediate. Among six concept SACs, Sb- Bi-atom-supported identified as most produce HCOOH, offering excellent energy efficiency against hydrogen evolution reaction.
