摘要
通过热分解法制备Ti/IrO2+MnO2阳极,研究水冷、空冷、氮气保护随炉冷(氮冷)及炉冷4种冷却方式对Ti/IrO2+MnO2阳极电催化活性及稳定性的影响。研究表明,水冷得到的Ti/IrO2+MnO2阳极具有最高的电催化活性,循环伏安电荷q*可到达140mC/cm2左右,但该阳极的稳定性最差;炉冷电极及氮冷电极的催化活性及稳定性均较差;空冷阳极具有较高的电催化活性,循环伏安电荷q*可到达118mC/cm2,且稳定性是4种电极中最高的。综合分析,空冷是比较合理的冷却方式,它能确保Ti/IrO2+MnO2阳极在具有良好的电催化活性的同时又拥有最高的稳定性。
Through using thermal decomposition method to prepare Ti/IrO2＋MnO2 anodes, studying the effect of water cooling, aircooling, furnace cooling with nitrogen and furance cooling these four cooling ways on the electrocatalytic activity and stability of Ti/IrO2＋MnO2 anodes. And the study showed that Ti/IrO2＋MnO2 anodes which was obtained by water cooling have the highest electrocatalytic activity, at the same time its anodic voltammetric charge （q＊） can reach to 140mC/cm2 , however the stability of that anodes were the worst both the catalytic activity and stability of furnace cooling electrode and nitrogen cold electrode ware fairly bad; air cooling anode have a higher electrocatalytic activity, and its anodic voltammetric charge （q＊） can reach to 118mC/cm2 , as well as its stability was the highest of all the four anodes. From the comprehensive analysis, air cooling way not only can certain the catalytic activity of the anode, also can ensure the anode has the best stability.
