Study on Structure and Properties of Ti/Pb-PANI-WC Inert Anodes

Article Preview

Abstract:

Pb-PANI-WC inert anodes were prepared by direct current and pulse electrodeposition of PANI (conductive polyaniline) and WC particles with Pb2+ on the surface of titanium (Ti) substrate. The anodic polarization curves, cyclic voltammetry curves and Tafel polarization curves were measured in the solution of 50 g/L Zn2+, 150 g/L H2SO4 and 35°C, and the kinetic parameters of oxygen evolution, voltammetry charge, corrosion potential and corrosion current density have been obtained. The surface morphologies of the coating were investigated by using scanning electron microscope(SEM).The results show that the inert anodes prepared by pulse electrodeposition possess lower overpotential of oxygen evolution, higher electrocatalytic activity, and better reversibility of electrode reaction and corrosion resistance.
