ZNO/TIO2 and ZNO/NB2O5 as effective systems for the treatment of enteric bacteria and commercial dyes

In this study, ZnO/TiO2 and ZnO/Nb2O5 photocatalysts were evaluated in the river pollution remediation wastewater treatment from textile factories, thus, target pollutants selected for study enteropathogenic bacteria commercial dyes. The mixed oxide systems extensively analyzed order to explore their physicochemical properties. From analysis, it was found that coupling of two oxides did not modify crystallinity pristine semiconductors. As a result, XRD Wurtzite phase, hexagonal anatase phases identified ZnO, Nb2O5, TiO2 photocatalyst, respectively. Using UV-Vis DRS, higher absorption visible region electromagnetic spectrum observed, along with decrease band gap value these materials. results photocatalytic activity evaluation showed ZnO Nb2O5 increased effectiveness total organic carbon (TOC) E. Coli elimination. 83% TOC elimination 64% coli achieved using photocatalyst water samples polluted river.
