文摘

A novel heterostructured photocatalyst AgTaO3/AgBr was constructed with highly enhanced visible light driven photocatalytic activity. The matching of the electronic structure between AgTaO3 and AgBr induced an efficient separation of photogenerated charge carriers. Photogenerated electrons, O2−, and OH active species dominate the degradation of methyl orange.
