Interfacial coupling of semiconductor with metal has been demonstrated for inactivation of E. coli. Fe doped ZnO was synthesized by sol–gel method that resulted in enhanced absorbance in visible region. Various concentrations of Cu were impregnated on Fe doped ZnO that eventually turned into copper oxide and the photocatalytic activity of this material was compared with noble metal (Ag) impregnated...
A novel ternary hybrid, ZnO-CdS-Ag was synthesized and photocatalytic inactivation of E. coli using UV and visible light irradiation was performed. The morphology of synthesized materials was validated by SEM, whereas the crystal details were evaluated by XRD and TEM. Diffuse reflectance was measured to determine the band gap and analyse the absorption range of light by synthesized composites. The...
