description The invention discloses a method for preparing a noble metal (palladiumpalladium, platinum, silver or gold) decorated nanometer ZnS/polyaniline composite photocatalyst, belonging to the technical field of chemical preparations. The method is characterized in that the photocatalyst is obtained through depositing the noble metals on the surface of the nanometer ZnS/polyaniline composite photocatalyst, and comprises the following steps of: (1) introducing a sulfur source by using a compound of conductive polymer polyaniline and Zn2+ as a matrix and using a coordination coordination conversion method to convert Zn2+ into sulfur-enriched nanometer ZnS among polyaniline links to prepare a composite system of the sulfur-enriched nanometer ZnS/polyaniline; and (2) reacting a noble metal ion with excessive S2-in the composite system of the sulfur-enriched nanometer ZnS/polyaniline to prepare the noble metal decorated nanometer ZnS/polyaniline composite photocatalyst by means of chemical deposition. The invention has t
