| Abstract: | This paper studied new insoluble anodes which are based on Ti,with the interface coated by solid solution of Sn,Sh,Ru,Ti oxides and the surface electrodeposited with manganese dioxide.the anodic characteristics in H_2SO_4 solution were studied by moving-potential sweep.the phase composition and surface topography of the electrode were analysed by X-ray diffraction and scaning electromicroscopy.In Cu-foil electrolysis and Ni electrowinning,the new anode material was compared with the Pb-Ag and Ru-Ti,and it was found to be a better anode
material for its high electrocatalytic activity,corosion resistance,and low cost. |
