hydrothermal and thermal sulfidation methods. They were characterized by XRD

S. It was found that the photoactivity decreased when the temperature in the preparing process increased. The photocatalyst prepared by coprecipitation method had the highest photoactivity. Its rate of hydrogen production without any cocatalysts was 350 μmol/h under visible light irradiation. Moreover
the rates of the photocatalysts prepared by hydrothermal and thermal sulfidation methods were only 120 μmol/h and 13 μmol/h
respectively.
