Abstract:
Palladium(Pd) is doped into traditional ruthenium oxide(RuO2) electrode to prepare a new dimensionally stable anode(DSA) electrode.This electrode is consisted of Sn/Sb oxide as its inter-layer and Ru/Pd oxide as its surface-layer(Ru-Pd/Sn-Sb/Ti).This electrode is used to dispose nitrobenzene(NB) wastewater.The degradation and conversion of NB is preliminarily studied and the optimal operating conditions of the electrode are ascertained as follows: the sintered temperature is 450 ℃,the coating oxides proportion is n(Ru)∶n(Pd)=0.65∶1,the numbers of the Sn/Sb mid-layers and the Ru/Pd surface layers are 5 and 18 respectively.The micro-morphology test and electrochemical test show that this electrode has better catalytic-activity,longer service-life and stronger bonding and finer grains.The NB water treatment experiment shows the Ru-Pd/Sn-Sb/Ti electrode can effectively remove and decompose the organics.
