Synthesis of Cadmium Oxide and its Electrochemical Detection of Pollutants

摘要

Cadmium oxide was synthesized using cadmium acetate and oleic acid as the precursor and capping agent, the main role of oleic acid to cap the formed cadmium oxide and to control the particle size. The formed cadmium oxide nanoparticles were characterized by using FT-IR, XRD,FE-SEM and cyclic voltammetry. The electrochemical detection of pollutants (4-Nitrophenol and 2-Nitrophenol) was carried out by coating the cadmium oxide onto the glassy carbon electrode (GCE) by drop coating method. The electrocatalytic performance of the modified GCE electrode was best with 4-Nitrophenol. In case of 2-Nitrophenol the electrocatalytic performance was not observed but increase in current response indicates the ability of modified electrode to be a useful one for sensing the environmental pollutants.
