Abstract The acrylamide and N,N$^{\prime}$--methylenediacrylamide were used to make a polyacrylamide gel from an aqueous solution of zinc acetate and silver nitrate. The characterization and the photocatalytic activities of nanometer--sized ZnO/Ag were studied by XRD, FT--IR and TEM. The results showed that because of polyacrylamide network the particle of ZnO/Ag crystalline was global, the even particle diameter size of nanometer--sized ZnO un--coated by Ag was about 15 nm, and the even particle diameter size of nanometer--sized ZnO/Ag about 45 nm. The degraded rate of methylene blue was 100\% when ZnO/Ag was used, and ZnO/Ag powders can be used repeadly.

Key words: inorganic nonmetallic material polyacrylamide gel method nano ZnO/Ag photocatalysis
