In order to solve the current energy and environmental crisis, the design of efficient catalyst materials is a highly effective solution. In this paper, the photocatalytic performance of TiO 2 /g-C 3 N 4 composites was improved by regulating their microstructure, such as by constructing nanosheet structures, defect sites, and contact interfaces. Although TiO 2 had limited activity in H 2 production under visible light irradiation, it could serve as an electron acceptor of g-C 3 N 4 , and it greatly increased the photocatalytic activity of g-C 3 N 4 . The optimal TiO 2 /g-C 3 N 4 composite showed good photocatalytic performance (436.3 μmol h −1 g −1 ), which was 23.8 and 3 times that of T400 and g-C 3 N 4 , respectively. The increased photocatalytic activity of the TiO 2 /g-C 3 N 4 composite could be attributed to the higher separation rate of the photogenerated charge carriers (PCCs), more active sites for the reaction, and a lower energy barrier than that of g-C 3 N 4 . Through many characterization and testing technologies, this work deeply studies the relationship between the fine structure and reaction mechanism of 2D/2D TiO 2 /g-C 3 N 4 , providing a new direction and understanding for the design and development of 2D materials with highly efficient activity.
