ZnO, Fe2O3 and CuO nanoparticles have been successfully grown, without the use of additives like surfactants, capping agent or complexing agent etc. by hydrothermal reaction technique. The structural, morphological, of ZnO, Fe2O3 and CuO nanoparticles were studied using Scanning electron microscopy (SEM). The photocatalytic degradation properties of ZnO, Fe2O3 and CuO nanoparticles were further studied by using UV-Vis spectroscopy. The resulting morphology of the end product can be regulated by changing the concentration of precursor and the time and temperature of the reaction. SEM throws light on the morphology of the as synthesized nanoparticles. UV-Vis spectroscopy gives evidence that the as synthesized Fe2O3 nanoparticles have narrow absorption width in UV range and broad absorption width in visible range and thus can be useful for the photocatalytic reactions in visible light.The highest photo catalytic efficiency was observed for the particles of Fe2O3 as compared to CuO and ZnO nanoparticles.
