Effect of pH Variation to Synthesis CuO Nanoparticles for Photocatalytic Studies

Mohamed Jaffer Sadiq

Abstract


In last few years, there are many methods developed to synthesis CuO nanoparticles. In this present research work, CuO nanoparticles were prepared by chemical precipitation method using cheap chemicals such as copper chloride dihydrate (precursor salt) and sodium hydroxide (precipitating agent) at varying pH like 7, 9 and 11 (adjusting pH at HCl or NaOH). The prepared materials were dried at 65oC for 2 hours to get phase pure product. The CuO nano particles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDAX) techniques. Photocatalytic degradation studies of Alizarin Red S using CuO nanoparticles were studied and reported.

Key words: chemical precipitation method, nanoparticles, pH variation, characterization, photocatalytic degradation.
