Ammonia is one of the common inorganic pollutants in surface waters. It can come from a wide range sources through discharge wastewater (industry, agriculture, and municipal waters). Catalytic ozonation reaction efficiently remove ammonia nitrogen without introducing other improve selectivity products by controlling conditions. Catalysts based on silver nanoparticles (Ag NPs) have shown excellent O3 decomposition performance; therefore, they are promising catalysts for catalytic due to their high reactivity, stability, N2. In this study, we synthesized well-defined using modified alkaline polyol method then dispersed them solid oxide supports (Fe3O4, TiO2, WO3). Before being deposited support, were characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-VIS spectroscopy. The obtained catalysts, Ag_Fe3O4, Ag_TiO2, Ag_WO3 scanning (SEM), BET area analysis, spectroscopy, temperature-programmed reduction (H2-TPR), desorption (TPD) CO2 NH3. has been demonstrated that nature support significantly influences physicochemical properties as well performance reaction.
