Abstract

Abstract

Ti₄O₇, due to its high electrochemical stability and electronic conductivity, has been widely used in electrochemistry and has shown excellent performance. In this paper, a high-performance carbon modified Ti₄O₇ electrode membrane prepared by extraction and filtration method was used in a flow-through filtration system to achieve efficient phenol degradation. SEM, XPS, and XRD were used to characterize the morphology and crystal structure of carbon materials with different loading ratios and structures. The effects of different catalysts and carbon material loading, applied voltage, solution pH, and flow rate on the degradation efficiency of phenol were investigated. The results showed that the oxidation flux of the electrode film in the circulation system reached 1208.5 mg/(h·m²), when the addition of acetylene carbon black (ATCE) was 5%, the voltage was 4 V, the solution pH was 3.0, and the flow rate was 1.5 mL/min. Comparing the electrochemical performance test results before and after the loading of carbon material, it was found that the presence of carbon material between the Ti₄O₇ crystals significantly improved the electron transfer rate. This paper further confirms the electrode surface properties and the relationship between the anode electric catalytic oxidation performance, and provides a new path for the electrode reactor optimization
