The value of current density and the apparent active energy of electroreduction of substituted nitrobenzene depend on the electronic effect of substituted group and space resistance. o,m,p-chloronitrobenzene will be electroreduced to azoxy compounds by taking three electrons, o,m-nitrotoulene and o,m-nitrobenzoic acid will be reduced to phenol compounds by taking four electrons, and p-nitrotoulene will be reduced to the aniline by taking six electrons. According to these results, the electroreduction mechanism of the substituted aryl nitro-compounds was studied in detail.

在电还原过程中，还原峰电流和表观活化能的大小均与取代基的电子效应和空间位阻相关，同时取代硝基氯苯得3个电子将还原生成氧化偶氮苯类化合物：邻、间硝基甲苯、硝基苯甲酸得4个电子将还原生成酚类化合物；对硝基甲苯得6个电子将还原生成胺类化合物，在此基础上，探讨了各芳族硝基化合物的电还原机理。
