g-C₃N₄ and In₂O₃:Sn(ITO) photocatalysts were synthesized by low-temperature calcined method. A little nanosized ITO as an effective cocatalyst was loaded onto g-C₃N₄ particle surface by electrostatic attraction. The photocatalytic activity of ITO/g-C₃N₄ was performed by its H₂ evolution performance under uv-vis irradiation while alcohol was used as a sacrificial agent, and the photocatalyst was characterized by XRD, SEM, TEM and UV-Vis absorption spectrum. The results showed that the photocatalytic activity of ITO/g-C₃N₄ was superior to that of pure g-C₃N₄, and loaded ITO can improve the interfacial electron transfer and the H₂ evolution. When the amount of loaded ITO was 4%(wt), the stable average hydrogen evolution rate was about 350 μmol·g^-1·h^-1.
