Highly Active Oxygen Evolution Integrating with Highly Selective CO₂-to-CO Reduction.

ABSTRACT: Artificial carbon fixation is a promising pathway for achieving the carbon cycle and environment remediation. However, the sluggish kinetics of oxygen evolution reaction (OER) and poor selectivity of CO₂ reduction seriously limited the overall conversion efficiencies of solar energy to chemical fuels. Herein, we demonstrated a facile and feasible strategy to rationally regulate the coordination environment and electronic structure of surface-active sites on both photoanode and cathode. More specifically, the defect engineering has been employed to reduce the coordination number of ultrathin FeNi catalysts decorated on BiVO₄ photoanodes, resulting in one of the highest OER activities of 6.51 mA cm^-2 (1.23 V_RHE, AM 1.5G). Additionally, single-atom
