Abstract
We report herein synthesis of Zr doped NTiO2 prepared by simple microwave assisted method From XRD study it reveals that Zr+4 ions are substituted in the lattice of NTiO2 with average crystallite size of 12 nm The interplanar distance d obtained from HRTEM was found to be 035 nm which confirms the anatase phase of TiO2 An optimal Zr content shows lowest PL intensity which supports the reduction in recombination rate of charge carrier species Moreover to know photocatalytic activity we have tested NTiO2 and Zr doped NTiO2 nanomaterials for degradation of methyl orange MO and gemifloxacin mesylate GFM antibiotic drug under UV light The photodegradation of MO and GFM were found to be 94 and 89 within 60 and 40 min respectively An increment of 45 in the photodegradation of MO by 05 mol Zr doped TiO2 was obtained as compared to NTiO2 The probable mechanism for Zr doped NTiO2 is also discussed Photodegradation of drug was also supported by decrease in antibiotic activity of photodegraded drug sample against E coli
