Acceleration of Photocatalytic CO Reduction at Intimate Interface in AgBr/BiOBr Heterojunctions via a Co-anion Strategy.

Constructing heterojunctions with strong interfacial interactions can accelerate the transfer and separation of photogenerated charge carriers. However, finding a simple strategy to construct tightly connected heterojunctions remains a major challenge. In this work, AgBr/BiOBr S-scheme heterojunctions were designed via a straightforward co-anionic strategy without using a solvent.
