Abstract
The objective of the research was mainly focused on the synthesis of ZnO and MgO nanoparticle by low temperature solution combustion method using Urea as fuel. The accurate size and morphology of the nanoparticles were studied from Transmission Electron Microscopy (TEM) to assess the structure of the ZnO and MgO particles. The phase composition of the Synthesized ZnO and MgO nanoparticles were confirmed from powder X-ray diffractometer (PXRD). The electrochemical impedance spectroscopy (EIS) shows the charge transfer capacity was more in the electrode with zinc oxide compared to magnesium oxide. Cyclic voltammetry studies were performed to ascertain the electrochemical reversibility of electrode.We evaluate the photocatalytic activity of nanoparticles shows rapid color removal and reduction in the concentration of dyes.
