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.
