Abstract

A series of type-II BaSnO₃/g-C₃N₄ heterojunction composites are prepared by anchoring BaSnO₃ on g-C₃N₄ via a facile solvothermal method. BaSnO₃ is applied as an electron transport promoter in the field of photocatalytic H₂ production under visible light for the first time. BaSnO₃ shows excellent performance in collecting and transferring photogenerated electrons from g-C₃N₄ to reactive sites, thus effectively inhibiting the recombination of photogenerated electron–holes. Consequently, the photocatalytic H₂-production activity of BaSnO₃/g-C₃N₄ composite is enhanced up to 3.2 times compared to that of pristine g-C₃N₄. This work provides a meaningful reference for the application of electron transport materials in the field of photocatalysis.
