SYNTHESIS OF NANO PARTICLES

Abstract

In the present study, electrochemical method is utilized for the synthesis of copper succinate nanoparticles. The process uses succinic acid as an electrolyte and copper sheets were used as an electrode. Relevant properties of synthesized nanoparticles are characterized to validate the results with the research papers. Characterization results reveals that copper succinate formed for different experimental parameters like pH, concentration (C0), current density (I) has copper oxide in main phase. SEM analysis shows the synthesized nanoparticles were of cylindrical morphology. At optimum condition of 0.15M concentration of electrolyte solution, 7 pH of the solution, 0.1A of current density nanoparticle shows maximum productivity before and after calcination. Variation of electrode thickness have also been investigated and showed that it does not have any effect on the productivity. These copper succinate nanoparticles are further calcined to form copper oxide nanoparticles. An effective catalytic effect of synthesized nanoparticles were investigated on the degradation on Methylene blue and Rhodamine-B dye. Maximum degradation of 91% was seen for Methylene blue dye within 1 hr whereas Rhodamine-B shows a 94% degradation within 3 hr. It was observed that Methylene blue dye has high reaction rate compared to Rhodamine-B dye with rate constants 1.975 hr-1 and 1.0168 hr-1 for both dyes. Recovery of the nanoparticles were seen and was around 70-78% with the degradation efficiency of about 90-92% for both dyes after several usage of the nanoparticles. Effect of nanoparticle dosage has also been investigated
