Abstract Limiting the formation of CO adsorbed species (CO ads ) or promoting its removal during formic acid oxidation reaction (FAOR) is essential to improving activity and stability Pd‐based catalysts. In this work, an innovative strategy proposed adjust Schottky barrier height (SBH) through band structure design for effective utilization photogenerated carriers remove , thereby FAOR performance Specifically, electronic Pd adjusted by loading on WO 3 nanosheets incorporating different amounts Sn reduce Fermi level pinning SBH. The accelerated migration electrons promotes accumulation holes valence . constructed effectively regulates catalyst optimizes adsorption energy intermediate CO, thus inhibiting indirect pathway. Therefore, optimal 1 /WO provides higher efficiency carrier‐assisted electrocatalytic FAOR, with a mass 2262.3 mA mg −1 outperforming most This work offers novel approach designing catalysts, combining modulation carrier assistance advance performance.
