Bottom-up construction of surface frustrated Lewis pairs on FeOOH-modified In2O3−x for enhanced photocatalytic CO2 reduction

Abstract

An FeOOH-modified In₂O_3−x photocatalyst was constructed via a bottom-up synthetic strategy. The surface-anchored FeOOH species facilitate the formation of surface frustrated Lewis pairs (FLPs) on the In₂O_3−x matrix, promote the generation and migration of photogenerated carriers, and thereby contribute to excellent photocatalytic CH₄ production under sunlight irradiation.
