摘要Withgood chemical stability and more active sites, the Ti/PbO2 electrode is a commonly used electrode material in the electrochemicaloxidation reaction. However, drawbacks of large surface cracks andcorrosion during redox processes still exist in conventional Ti/PbO2 electrodes. Herein, a PbO2 electrode modifiedwith reduced graphene oxide and surfactant OP-10 (OP-10&rGO-PbO2) was prepared by electrodeposition with Ti/SnO2-Sb2O3 as a substrate. The addition of rGOwas helpful in forming a dense surface of PbO2 and avoidingthe side reaction of oxygen evolution during wastewater degradation.It has higher oxygen evolution potential and a longer service lifetime.In addition, the acrylamide (AA) degradation conditions were optimized.It was proved that the OP-10&rGO-PbO2 electrode hasa good industrial application prospect in dye wastewater. The chemicaloxygen demand removal rate of dye wastewater can reach 89% within120 min. Furthermore, the degradation mechanism of AA was also discussedby gas chromatography-mass spectrometry technique, and thepossible degradation path was also proposed.
