Copper oxide nanoparticles have been successfully synthesized by microwave assisted precipitation method. Different precursors like copper chloride, copper nitrate and copper sulphate were used for synthesis of CuO nanoparticles with different shape, size and catalytic activity. Sodium hydroxide acts as a capping agent and ethanol as solvent for the synthesis. The XRD study was conducted to confirm the single phase monoclinic structure of as-synthesized and annealed CuO nano particles. The morphology of the as-synthesized and annealed CuO samples was analyzed by high resolution field emission scanning electron microscope. Fourier transform infrared spectroscopy was done for all the synthesized CuO nanoparticles for functional group characterization. The wide band gap and photocatalytic activity were studied by UV-Visible spectroscopy. The photocatalytic degradation of Methylene blue (MB) and Rhodamine B (RhB) dyes in aqueous solution were investigated under UV light (254 nm). In all the cases annealed samples showed good catalytic activity compared to as-synthesized CuO nanoparticles. The CuO nanoparticles from CuCl2 precursor act as excellent photocatalyst for both MB and RhB compared to CuNO3 and CuSO4.
