Surface charge localization and inferior transfer efficiency seriously restrict the supply of reactive hydrogen reaction dynamics CO2 photoreduction performance photocatalysts. Herein, chemically bonded BiVO4/Bi19Cl3S27 (BVO/BCS) S-scheme heterojunction with a strong internal electric field is designed. Experimental density function theory calculation results confirm that elaborated accelerates vectorial migration photogenerated charges from BiVO4 to Bi19Cl3S27 via interfacial chemical bonding interactions (i.e., Bi-O Bi-S bonds) between Bi atoms BVO S BCS or O under light irradiation, breaking barrier surface Bi19Cl3S27, further decreasing energy generation, absorption activation. The separation carriers much more efficient counterpart individual in BVO/BCS system. As result, exhibits significantly improved continuous photocatalytic for reduction 24 h CO yield reaches 678.27 μmol·g−1. This work provides an atomic-level insight into kinetics mechanism heterojunction.
