内容記述 | The decrease in thermal decomposition temperature led to the amorphization of RuO2, and nano RuO2 particles were uniformly dispersed in amorphous Ta2O5 matrix. Such nano particles induced the increase in effective surface area for oxygen evolution and change in rate determining step, resulting in a significant decrease in oxygen overpotential. This excellent achievement induced a significant decrease in cell voltage of 0.7 V compared to lead alloy anodes and a voltage reduction of 37 % was achieved for copper electrowinning. Another distinct feature of the amorphous anodes is that nano RuO2 particles increase the overpotential of the unwanted side reaction on the anode, so that the anodic deposition of PbO2 can be completely inhibited. Therefore, the amorphous RuO2-Ta2O5/Ti anodes developed in this thesis have a high possibility to improve the purity of electrowon metal, reduce the maintenance of electrolysis process, prolong the lifetime of the anode, and make a low impact to environment. | |||||
