Table_1_The Improvement of Photocatalysis H2 Evolution Over g-C3N4 With Na and Cyano-Group Co-modification.docx

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 H₂ evolution, its H₂ evolution rate was obviously improved. Furthermore, it also kept excellent stable capacity of H₂ 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.
