研究了在铂和PbO_2电极上对硝基苯胺电合成4，4’-二硝基偶氮苯的影响因素，确定了最佳工艺条件。电合成的最大转换效率为95%，与纯β-PbO 2电极。结果发现，PbO 2电极的电催化活性取决于它的α/β比和它的结晶度。同时还研究了外加碱和水对转化效率的影响。
Parameters which affect the electrosynthesis of 4,4'-dinitroazobenzene from p-nitroaniline on platinum and PbO2 electrodes were investigated and optimum conditions were determined. Maximum conversion efficiency for electrosynthesis was 95% with a pure beta-PbO2 electrode. It was found that the electrocatalytic activity of a PbO2 electrode depends upon its alpha/beta ratio and its degree of crystallinity. The effects of the added base and water on the conversion efficiency were also elucidated.
