1. A method of water decontamination, comprising:
contacting sulfur-doped Ag2WO4 nanoparticles with an aqueous solution to form a mixture, wherein the aqueous solution comprises one or more pollutants,
mixing the mixture; and
collecting a filtrate, wherein the filtrate has less of the one or more pollutants than the aqueous solution,
wherein the amount of sulfur present in the sulfur-doped Ag2WO4 nanoparticles is in a range from 5 to 30 wt. % of the total weight of the sulfur-doped Ag2WO4 nanoparticles, and
wherein the sulfur-doped Ag2WO4 nanoparticles have an average particle diameter ranging from 2 to 40 nm.
