Interfacial construction of P25/Bi₂WO₆ composites for selective CO₂ photoreduction to CO in gas-solid reactions.

ABSTRACT: Photocatalysis provides an attractive approach to convert CO₂ into valuable fuels, which relies on a well-designed photocatalyst with good selectivity and high CO₂ reduction ability. Herein, a series of P25/Bi₂WO₆ nanocomposites were synthesized by a simple one-step in situ hydrothermal method. The formation of a heterojunction between Bi₂WO₆, 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 CO₂ selective photoreduction to CO. The maximum CO yield of the P25/Bi₂WO₆ heterojunction under simulated solar irradiation was 15.815 μmol g^-1 h^-1, whi
