Abstract Construction of heterostructured photocatalysts is a feasible method for improving hydrogen production from water splitting because of its good charge transport efficiency. Herein, we coupled the Ti-MOFs (TiATA) with metal-free graphitic carbon nitride (g-C3N4) to synthesize composites, g-C3N4@TiATA, in which a heterostructure was formed between g-C3N4 and TiATA. The establishment of heterojunctions not only broadens the light absorption range of g-C3N4@TiATA (490 nm) by contrast with g-C3N4 (456 nm), but also greatly accelerates charge migration. Photocatalytic studies present that the construction of heterostructure steering the charges flow from g-C3N4 to TiATA and then delivery to the cocatalyst of Pt nanoparticles, exhibiting an impressively photocatalytic hydrogen production rate (265.8 μmol·h−1) in assistance of 300 W Xenon lamp, which is about 3.4 times as much as g-C3N4/Pt.
