BiVO ₄ ‐Based S‐Scheme Heterojunctions for Photocatalytic Co ₂ Reduction

Abstract

Under energy and environmental challenges, photocatalytic CO 2 reduction (PCR) has received much attention as a sustainable and clean energy conversion technology. BiVO 4 is noted for its excellent photochemical stability and suitable bandgap width. However, single BiVO 4 is still plagued by rapid carrier recombination and low reduction during PCR. Constructing an S‐scheme heterojunction represents an effective strategy to address these challenges. This article summarizes the up‐to‐date advancements in BiVO 4 ‐based S‐scheme heterojunctions for PCR. The design strategies, synthesis methods, and characterization means of these heterojunctions are explored. The applications of S‐scheme heterojunction constructed by coupling BiVO 4 with metal−organic frameworks, carbon‐based materials, perovskites, and metal oxides/sulfides in PCR are highlighted. This review proposes novel design strategies of S‐scheme heterojunctions for efficient PCR.
