Epitaxial growth of BiTiO-BiPO Z-scheme heterojunction to promote carrier transfer for photocatalytic oxidation of NO.

The lack of compactness in heterojunction interfaces and poor charge separation is a great challenge in developing high-efficiency heterojunction photocatalysts. Herein, a novel BiTiO-BiPO heterojunction was successfully prepared for the first time by epitaxial growth of BiPO on the surface of BiTiO nanosheets. The optimized BiTiO-BiPO-0.
