Disclosed are the metallic sulfide photocatalyst and its preparation method. The photocatalyst includes at least one soluble metallic salt and a sulfide with the oxidation state of S atom ≦+4. The photocatalyst is afforded by reacting the sulfide with the at least one soluble metallic salt dissolved in the complexing agent. Additionally, the photocatalyst further is customized with co-catalyst such as RuCl to form Ru-carried metallic sulfide photocatalyst. The metallic sulfide photocatalyst and Ru-carried metallic sulfide photocatalyst are capable of effectively reducing CO
