Enhanced photoelectrochemical activities for water oxidation and phenol degradation on WO₃ nanoplates by transferring electrons and trapping holes.

ABSTRACT: It is highly desired to improve the photoelectrochemical (PEC) performance of nanosized WO₃ by artificially modulating the photogenerated electrons and holes simultaneously. Herein, WO₃ nanoplates have been successfully prepared by a simple one-pot two-phase separated hydrolysis-solvothermal method, and then co-modified with RGO and phosphate acid successively by wet chemical processes. Subsequently, the as-prepared WO₃-based nanoplates were immobilized on the conductive glasses to explore the PEC activities for both water oxidation to evolve O₂ and phenol degradation. It is clearly demonstrated that the co-modified WO₃ nanoplates exhibit significantly improved PEC activities compared with pristine WO₃, especially for that w
