摘　　要：A new type of photoelectrochemical cathodic protection technology(a combination of seawater corrosion and biological fouling resistance)is being actively researched to alleviate the serious corrosion of marine metal materials.At present,there is almost no research on anti-corrosion and anti-fouling dual functional materials.In this paper,Cu_(2)ZnSnS_(4)is attached to the surface of TiO,nanotubes through a one-step hydrothermal method for modification.The results indicate that when the hydrothermal reaction time is 24 h,Cu_(2)ZnSnS_(4)/TiO_(2)nanocomposite material exhibits excellent performance in coupling with the protected 304 SS,with its open circuit potential shifts negatively to-1.04 V.This material improves the separation efficiency of photogenerated electrons and effectively improves the photochemical cathodic protection of 304 stainless steel.The high removal rate of Staphylococcus aureus(up to 93%)of the as-prepared samples also proved that it has the effect of the anti-biological fouling.为了缓解金属材料在海洋中的严重腐蚀,一种新型的光电化学阴极保护技术(海水腐蚀和生物防污相结合)正在积极研究中,因此需要研究防腐防污双功能材料。本文采用一步水热法将Cu_(2)ZnSnS_(4)附着在TiO_(2)纳米管表面进行改性。结果表明,当水热反应时间为24 h时,Cu_(2)ZnSnS_(4)/TiO_(2)纳米复合材料与被保护的304 SS不锈钢具有良好的耦合性能,其开路电位负移至-1.05 V,提高了光生电子的分离效率,有效增强了304 SS不锈钢的光化学阴极保护。制备的样品对金黄色葡萄球菌的去除率高达93%,也证明了其具有抗生物污损的作用。
