Résumé

The type II heterostructured g-C ₃ N ₄ /ZnO nanorods arrays (NRAs) with intimate interface connection were successfully synthesized via a light-assisted method for photocatalytic H ₂ production. Such type-II heterojunction between g-C ₃ N ₄ and ZnO not only promotes the charge separation and transport but also extends light absorption to the visible light region. In addition, the high physicochemical stability of g-C ₃ N ₄ layer keeps ZnO from photocorrosion during the reaction. Consequently, the heterostructured g-C ₃ N ₄ /ZnO NRAs demonstrate enhanced photocatalytic H ₂ performance. In particular, the highest photocatalytic activity enhancement of g-C ₃ N ₄ /ZnO heterostructure is 3.3 times that of ZnO NRAs with a good stability of 85% retention rate after 5 cycles. Our work here presents an effective strategy to construct heterojunction between g-C ₃ N ₄ and metal oxide semiconductors for significantly enhanced photocatalytic H ₂ production.

N2 - The type II heterostructured g-C 3 N 4 /ZnO nanorods arrays (NRAs) with intimate interface connection were successfully synthesized via a light-assisted method for photocatalytic H 2 production. Such type-II heterojunction between g-C 3 N 4 and ZnO not only promotes the charge separation and transport but also extends light absorption to the visible light region. In addition, the high physicochemical stability of g-C 3 N 4 layer keeps ZnO from photocorrosion during the reaction. Consequently, the heterostructured g-C 3 N 4 /ZnO NRAs demonstrate enhanced photocatalytic H 2 performance. In particular, the highest photocatalytic activity enhancement of g-C 3 N 4 /ZnO heterostructure is 3.3 times that of ZnO NRAs with a good stability of 85% retention rate after 5 cycles. Our work here presents an effective strategy to construct heterojunction between g-C 3 N 4 and metal oxide semiconductors for significantly enhanced photocatalytic H 2 production.
