Semiconductor-based photocatalyst method in degrading pollutants is the outstanding way to overcome water pollution. In this study, the semiconductor material Ag doped ZnO (Ag/ZnO) was made in powder form using Zn(NO3)2.6H2O, AgNO3 and pineapple peel extract as Zinc source, Ag source and as bioreductant, resepctively. Ag/ZnO samples were synthesized with various percentages of Ag , namely, …
