ABSTRACT=<p>Na and cyano-group co-modified g-C<sub>3</sub>N<sub>4</sub> 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-C<sub>3</sub>N<sub>4</sub> was splitting water H<sub>2</sub> evolution, its H<sub>2</sub> evolution rate was obviously improved. Furthermore, it also kept excellent stable capacity of H<sub>2</sub> evolution and stability of chemical structure. Hence, this present study does not only develop an efficient strategy to boost photocatalytic property of g-C<sub>3</sub>N<sub>4</sub> based catalysts, but also provides useful guidance for designing more effective photocatalysts.</p>
