Abstract

A systematic study was carried out to investigate the reduction reaction mechanism of oxygen on pyrite surface using electrochemical techniques. The polarization curves showed two distinct regions, the Tafel region for superoxide formation and limiting current region for diffusion of dissolved oxygen to form hydrogen peroxide. These results were confirmed with a-c impedance measurements.
