Abstract
Copper oxide (CuO) and carbon functionalized copper oxide nanoparticles (c-CuO) had been successfully synthesized by simple thermal decomposition method. Copper oxide was prepared from CuSO4·5H2O and NaOH and carbon functionalized CuO was prepared from CuSO4·5H2O and starch. The physical microstructure and morphology of nanoparticles were characterized by X-ray diffraction and field emission scanning electron microscopy (FESEM). From the XRD observation, it is evident that the particle size of CuO was obtained as a nano size by this synthesis process and the FESEM image showed the morphology of both nanoparticles. The electrochemical performance of the CuO and carbon functionalized CuO was evaluated by cyclic voltammetry. The cyclic voltammogram shows c-CuO nanoparticles are more sensitive towards detection of uric acid when compared to CuO.
