F-B Co-Doped TiO₂ Nanosheets Bounded with Highly Active Anatase(001) Facets for Improved Photocatalytic Hydrogen Evolution

Abstract

F-B co-doped TiO₂ nanosheets with exposed anatase(001) facets were synthesized via a one-pot solvothermal method, and their photocatalytic hydrogen evolution performance was investigated. Characterization results confirm that this method effectively promotes the growth of the highly active anatase(001) facets and enhances visible and infrared light absorption while inducing oxygen vacancies. Under optimal conditions, the hydrogen evolution reaches 20.57 μmol after 10 h of ultraviolet-visible(UV-Vis) light irradiation, exceeding the commercial TiO₂ nanoparticles Degussa P25 by more than 10 times. These findings highlight the potential of F-B co-doped TiO₂ nanosheets for efficient photocatalysis.
