| Abstract | The photocatalytic activity of TiO2 and ZnO in the presence of MnO2, a particulate matter present in natural water and wastewater, has been studied. We found that a trace amount of MnO2 particles deactivated TiO2 photocatalysts, but its effect on the activity of ZnO was negligible. UV-visible diffuse reflectance spectra (DRS) and surface photovoltage spectroscopy (SPS) analysis implied that the interaction of MnO2 with TiO2 and ZnO could change the energetics of these two photocatalysts.
