摘要：
本发明公开了一种Ti/Sb-SnO2/Nd-nano TiO2-PbO2电极的制备及其降解活性蓝117的方法，属于电催化技术领域。一、对钛片预处理；二、在钛片上涂覆由组成:32gSbCl3，150gSnCl4·5H2O，50mL浓盐酸，300mL的n-C4H9OH的涂液，烘干和热分解，得镀有锡锑氧化物底层的电极；三、在组成为：Pb(NO3)2＝0.5mol/L、HNO3＝0.1mol/L、0.04MNd(NO3)3,NaF＝0.04mol/L和nano TiO2＝8gL-1的电镀液中采用5mAcm-2电镀1.5h，得Ti/Sb-SnO2/Nd-nano TiO2-PbO2电极；四、电催化降解污水中有机染料活性蓝117。采用本发明的方法制备得到的电极，镀层内应力大幅下降，晶体颗粒精细致密，同时提高二氧化铅电极的使用寿命与催化活性。
摘要（英）：

The invention discloses a method for preparing a Ti/Sb-SnO2/Nd-nano TiO2-PbO2 electrode and degrading reactive blue 117 through the Ti/Sb-SnO2/Nd-nano TiO2-PbO2 electrode, and belongs to the technical field of electro-catalysis. The method includes the steps that firstly, a titanium sheet is pretreated; secondly, the titanium sheet is coated with a coating solution composed of 32 g of SbCl3, 150 g of SnCl4 5H2O, 50 mL of concentrated hydrochloric acid and 300 mL of n-C4H9OH, drying and thermal decomposition are carried out, and an electrode plated with a tin-antimony oxide bottom layer is obtained; thirdly, 5mAcm<-2> electroplating is carried out for 1.5 h in an electroplating solution composed of 0.5 mol/L of Pb(NO3)2, 0.1 mol/L of HNO3, 0.04 mol/L of 0.04MNd(NO3)3,NaF and 8 gL<-1> of nano TiO2, and the Ti/Sb-SnO2/Nd-nano TiO2-PbO2 electrode is obtained; and fourthly, organic dye, namely the reactive blue 117 in waste water is degraded in an electro-catalysis mode. According to the electrode prepared through the method, the internal stress of a plating layer is greatly reduced, and crystal particles are fine and compact; meanwhile, the service life of the PbO2 electrode is prolonged, and the catalytic activity of the PbO2 electrode is improved.
