"photocatalysis involves interplay between surface charges/ charge transfer at catalyst-electrolyte interface... directly measures nanoscale surface charges (potential/ photovoltage) in liquid electrolyte environments using charged probe, isolating electrostatic forces from long-range interactions, mapping electric field distribution within electrical double layer... surface charges at solid-liquid interface create additional driving force, pulling photogenerated electrons to surface, driving charge transfer reaction"
