摘要
研究了热分解法和电沉积法制备二氧化铅电极的工艺,通过对苯酚的电解和生成羟基自由基的量,比较了两种方法制得的电极的催化性能,并比较了采用电沉积法制备电极时掺杂铋或镧对电极的催化性能的影响。实验结果表明,这4种电极都具有良好的电催化性能,并且明显降低了槽电压,且对苯酚的降解均符合一级反应动力学,电沉积法制得的电极的催化性能优于热分解法制得的电极,掺镧的电极优于无掺杂和掺铋的电极。
lead dioxide electrodes on Ti substrates were produced by thermal-deposition and electro-deposition.Electro-catalytic characteristics of the electrodes prepared by two methods above and the electrodes mingled with Bi or La prepared by electro-deposition were investigated through its degradation experiments of phenolic wastewater and the amount of hydroxyl radical.The experimental results showsd that the four electrodes all have good electro-catalytic characteristics,can reduce the voltage,and the electroche...
