AbstractA strong driving force for charge separation and transfer in semiconductors is essential for designing effective photoelectrodes for solar energy conversion. While defect engineering and polarization alignment can enhance this process, their potential interference within a photoelectrode remains unclear. Here we show that oxygen vacancies in bismuth vanadate (BiVO4) can create defect dipoles due to a disruption of symmetry.

Over the past decade, there has been intensive exploration into incorporating metal single atoms into photocatalysts, leading to the formation of single-atom catalysts (SACs) for various reactions.1, 2 Due to unique low-coordination environment and unsaturated configuration, it offers remarkable potential to increase reaction rates, boost selectivity, and prolong stability.3 However, most studies focus on transition-metal-based single atoms catalysts (TM-SACs) with the intension to utilize...
