摘要
采用电沉积法和热形成法制得钛基二氧化铅电极,并对这两种电极的电催化性能进行比较,同时通过电沉积法所得电极考察了电流、电源和抑制剂三种因素对产生羟基自由基的影响。实验结果表明,电沉积法所得电极具有良好的电催化性能;大电流和交流电源有利于羟基自由基的产生;CO32-、PO43-、CH3COO-抑制剂存在时会消耗掉产生的羟基自由基。
Lead dioxide electrodes of Ti substrate were prepared by electro-deposition and thermal-formed, and the electrocatalytic characteristics of electrodes were compared in this paper. In the meantime, the experimental results showed that the electro-catalytic characteristics of the electrode by electro-deposition was better; the stronger current and AC power supply were propitious to the generation of hydroxyl radicals; the generation of hydroxyl radicals was limited when inhibitors existed such as CO3^2- ,PO4^3- ,CH3COO- and so on.
