Abstract

The present study highlights the importance of anodes in electrocatalytic oxidation processes, with a focus on providing new insights into the modifications of Ti/SnO₂ anode to enhance its performance and lifetime service. Modifications with dodecyl sulfate surfactant, silicon carbide nanoparticles, and silica interlayers were thoroughly investigated to achieve this goal. The modified electrodes were thoroughly characterized in terms of morphology, crystalline structure, surface composition, and electrochemical properties. Electrochemical evaluations revealed substantial improvements in oxygen evolution potential, conductivity, service lifetime, and electrocatalytic performance for all modified electrodes. Among the investigated modifications, the Ti/SiO₂/SnO₂ electrode exhibited the most improvement in all aspect, particularly in charge transfer resistance and service lifetime. Notably, this electrode had a 4.12-fold increase in service lifetime compared to the unmodified Ti/SnO₂, making it a very promising candidate for practical applications in electrocatalytic oxidation processes.

增强电催化性能的Ti/SnO2电极：修饰的新见解

本研究强调了阳极在电催化氧化过程中的重要性，重点是就如何改进 Ti/SnO2 阳极以提高其性能和使用寿命提供新的见解。为实现这一目标，研究人员对十二烷基硫酸盐表面活性剂、碳化硅纳米颗粒和二氧化硅夹层进行了深入研究。改性后的电极在形态、晶体结构、表面成分和电化学性能方面都得到了全面的表征。电化学评估结果表明，所有改性电极的氧进化电位、电导率、使用寿命和电催化性能都有显著提高。在所研究的改性电极中，Ti/SiO2/SnO2 电极在各方面的改进最大，尤其是在电荷转移电阻和使用寿命方面。值得注意的是，与未改性的 Ti/SnO2 相比，这种电极的使用寿命延长了 4.12 倍，因此很有希望在电催化氧化过程中得到实际应用。
