Interfacial construction of P25/BiWO composites for selective CO photoreduction to CO in gas-solid reactions.

Photocatalysis provides an attractive approach to convert CO into valuable fuels, which relies on a well-designed photocatalyst with good selectivity and high CO reduction ability. Herein, a series of P25/BiWO nanocomposites were synthesized by a simple one-step hydrothermal method. The formation of a heterojunction between BiWO, which absorbs visible light, and P25, which absorbs ultraviolet light, expands the utilization of sunlight by the catalysts, and consequently, leads to a remarkably enhanced CO selective photoreduction to CO.
