Water pollution hazardous pollutant compounds is often found in the industrial sector. This study aims to increase the photocatalytic activity of ZnO for the degradation of 4-nitrophenol pollutants in wastewater. The method used in this study is the nanoparticle biosynthesis method that utilizes plant extracts. ZnO material is doped with (Ag, Se, and S) using matoa leaf extract and microwave irradiation heating. UV-Vis spectroscopy shows an absorption peak of 352-359 nm with a band gap energy of 2.57-2.85 eV. The smallest band gap energy, namely the ZnO:SeS_1.5Ag sample, when Ag doping increases, light absorption decreases. The hexagonal wurtzite crystal structure is seen in XRD with a shift in the diffraction peak to the left. The higher the doping percentage, the smaller the crystal size. while SEM displays a flower morphology with particles shrinking as Ag doping increases. EDS confirmed the presence of Zn, O, Ag, Se, and S. The O element only had one peak as a doping with a very small peak. The ZnO:SeS_1.5Ag sample was the fastest degradation within 120 minutes with the largest decrease in absorbance. Ag doping enhanced the degradation of 4-Nitrophenol under UV light, with the highest efficiency in ZnO:SeS_1.5Ag (95.98%) and a reaction rate of -1.78x10-2 min⁻¹. This study demonstrated that the biosynthesis of ZnO with doping (Ag, Se, and S) increased the effectiveness of the photocatalyst in the degradation of 4-Nitrophenol, opening up opportunities for environmentally friendly applications for industrial wastewater treatment.
