摘要：

Na and cyano-group co-modified g-C3N4 was easily synthesized and its physicochemical property was completely analyzed. The results manifested that Na and cyano-group modification could heighten visible light absorbed ability and accelerate photoinduced charge separation. When resultant Na and cyano-group co-modified g-C3N4 was splitting water H-2 evolution, its H-2 evolution rate was obviously improved. Furthermore, it also kept excellent stable capacity of H-2 evolution and stability of chemical structure. Hence, this present study does not only develop an efficient strategy to boost photocatalytic property of g-C3N4 based catalysts, but also provides useful guidance for designing more effective photocatalysts.
