In this paper, electrochemical performance of coated titanium anodes in the manganese electrowinning process are investigated. The turbid anolyte can be avoid by using coated titanium anodes compared to conventional Pb anodes, and the generation of manganese dioxide (MnO2) on anode can be also reduced. The deposited manganese dioxide layer on coated titanium anodes are uniform and compact after electrolysis by using Scanning electron microscopy (SEM), which is totally different from that on Pb anodes. The possible mechanism involving permanganate ion is proposed and confirmed by Square wave voltammetry (SWV) and in-situ ultraviolet-visible spectrophotometry (UV-VIS). Moreover, the cell voltage for coated titanium anodes is about 270 mV lower than that of traditional Pb anodes, exhibiting well energy saving effect. Linear sweep voltammetry and Tafel curves show that coated titanium anodes have lower Tafel slope and possess a better catalytic property for oxygen evolution reaction. Finally X-ray photoelectron spectroscopy (XPS) analysis manifests the Ru element can be oxidized to a higher valence state and has a blocking effect for active oxygen. Our results here offer some basic electrochemical data for the anode in electrolytic manganese system, and provide a promising path for replacing Pb anodes in electrolytic manganese industry.
