A hydrogen bond-based heterojunction photocatalyst, g-C3N4/melamine-cyanurate (gMC), was synthesized by a facile alkaline hydrothermal approach. The hydrogen bonds between the two substrates (Nsingle bondHOdouble bondC) provide not only an ultrafast pathway (hundreds of femtoseconds) but also an inner electric field for hole transfer from g-C3N4to melamine-cyanurate. Although only the g-C3N4moiety acts as a photocatalyst, the optimized composite presents approximately 5.4, 3 and 2.5 times higher photocatalytic activity than bulk g-C3N4in the decomposition of acetaldehyde and 2-propanol and the generation of H2by water splitting, respectively. In this paper, we demonstrate that hydrogen bonds can not only lower the interfacial barrier and separate redox sides but also control the direction of charge transfer, which enables the design of the photocatalytic mechanism.
