Abstract

Abstract

In this paper, the lead-antimony electrode with the tin-antimony intermediate layer, with high stability and electrocatalytic activity, was prepared by sol-gel method. The crystal structure, surface morphology, element composition, specific surface area and electrocatalytic performance of the electrode were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), energy-dispersive spectroscopy (EDS), Brunauer-Emmett-Teller(BET), linear sweep voltammetry test(LSV) and cyclic voltammograms test (CV). The electrocatalytic degradation performance and stability of different lead-antimony electrodes were investigated by taking di(2-ethylhexyl) phosphate ester wastewater as the research object. The results indicated that the coating of the lead-antimony electrode with tin-antimony intermediate layer was mainly pyrochlore-type composite oxide, higher roughness and compact structure of the intermediate layer were beneficial to improve the stability of the electrode, and the honeycomb microporous structure of the active layer made electro-catalytic performance significantly increased. The LSV and CV test indicated that the lead-antimony electrode with tin-antimony intermediate layer has better electrocatalytic activity and electrical conductivity, the COD removal rate of the electrode reached 92.5% after 2 hours of electrolysis, and the numerical value could maintain above 91% after 62 hours of continuous operation. The accelerated life of the electrode was up to 30 hours, and its actual life could reach 5.5 years when the accelerated life was converted into the service life, under the condition of the general industrial current density of 0.1 A/cm². The lead-antimony electrode with a tin-antimony intermediate layer has ideal electrocatalytic activity and stability, showing a good application prospect in the treatment of high-salt organic wastewater.
