Graphitic carbon nitride is a promising heterogeneous catalyst for light-induced generation of hydrogen. Here, we report the successful formation of nano-scaled carbon nitride structures on silicon, mitigating the known limitations of charge transport within bulky C–N networks. An efficient photoelectrochemical heterojunction is thereby realized, developed from earth-abundant materials only.
