Abstract :

Different doped metal oxides and metal sulphides like Ru:ZnS, Nb2O5/ZnO, Se:ZnS, Co:ZnO, Mo:ZnO, In2O3/SnO/ZnO are synthesized by electrochemical, hydrothermal and Cr2O3 by biological method which offers precise particle size, crystallinity and reduced band gap. All the synthesized Nanomaterials were characterized by XRD, SEM-EDS, UV-Vis, EDAX, IR, DLS and impedance spectroscopy. The photocatalytic activity for these nanocatalysts was evaluated by the degradation of textile dyes and textile industry effluents in aqueous solutions under UV and sunlight. Optimal catalyst loading, dye concentration, effect of temperature, pH and degradation by re-used samples were studied. The synthesized materials showed enhanced electrical, photo-voltaic and biological effect. A few synthesized nanocatalysts were used in the synthesis of organic compounds. The kinetics of photodegradation was studied with respect to measurement of COD. Anti-bacterial study was carried out by zone inhibition and fluorometric method. The polymer composites (PEO:Se/ZnS, PVA:Cr2O3, PVA:Mo/ZnO, PVA:Co/ZnO and PEO:Cd/ZnO etc.,) were prepared by casting method and its electrical, optical and viscosity properties were studied. The synthesized materials play an important role in waste treatment, photo-voltaic and biological applications.
