ZnWO/TiO composite films were fabricated on TiO substrate by hydrothermal method. The ZnWO nanorods-sensitized TiO coupled with 304 stainless steel was served as photoelectrode to study its anticorrosion effect for metal. Under visible light, the photocathodic protection ability of TiO and ZnWO/TiO composite film was measured by photoelectrochemical program on potentiostat. Open circuit potential variation result showed that sanmartinite ZnWO nanorods could enhance the photoelectrochemical activity of TiO, and the ZnWO/TiO composite films could absorb energy and store electrons to play a role in corrosion protection for metal.
采用水热法在 TiO 基底上制备了 ZnWO/TiO 复合薄膜。将 ZnWO 纳米棒敏化的 TiO 与 304 不锈钢偶联作为光电极，研究其对金属的缓蚀效果。在可见光下，通过恒电位仪上的光电化学程序测量 TiO 和 ZnWO/TiO 复合薄膜的光电阴极保护能力。开路电位变化结果表明，尖晶石型 ZnWO 纳米棒可以提高 TiO 的光电化学活性，而 ZnWO/TiO 复合薄膜可以吸收能量并存储电子，从而起到金属腐蚀保护的作用。
