Synthesis of Ag/ZnO nanostructures by different methods and investigation of their photocatalytic efficiency for 4-nitrophenol degradation

Ag/ZnO photocatalysts with different Ag loadings were prepared by photo reduction (AnZ2), chemical reduction (AnZ3) and polyacrylamide-gel (AnZ1) methods. Among the catalysts, the best photocatalytic performance for degradation of 4-nitrophenol was exhibited for Ag/ZnO prepared by polyacrylamide gel method.
