A facile one-step synthesis of ZnO quantum dots modified poly(triazine imide) nanosheets for enhanced hydrogen evolution under visible light†
Abstract
A heterojunction of crystalline poly(triazine imide) (PTI) nanosheets and ZnO quantum dots (QDs) (∼3 nm) was synthesized by a one-step ionothermal condensation of cyanamide. The resulting PTI/ZnO-QDs heterostructure exhibits a significantly enhanced H2 evolution to 63 times that of pure PTI and 3.4 times that of graphitic carbon nitride (g-C3N4) under visible light.
