Abstract

ABSTRACT Solar‐driven conversion of CO 2 and H 2 O into propionic acid remains challenging due to the complexity of multi‐electron transfer processes. Here, we couple frustrated Lewis pairs (FLPs), surface hydroxyls, and thermal excitation to build an electron‐rich Cu microenvironment for CO 2 ‐to‐propionic acid conversion. In the In(OH) 3 /CuO x @CF catalyst, oxygen vacancies (O v ) and neighboring Cu centers form O v ─Cu FLPs, while adjacent ─OH groups serve as cooperative Lewis bases and proton reservoirs. This architecture funnels photogenerated electrons from In(OH) 3 to Cu, stabilizes Cu δ+ (0 < δ
