摘　　要：以红汞 (mercurochrome)为敏化剂 ,采用新方法制备染料敏化的TiO2 光电极。在压力下 ,将红汞和TiO2 的混合体系压制 ,直接得到红汞敏化的TiO2 光电极。光电极瞬态光电流和组装的光电化学池的I V曲线表明 ,其短路光电流和开路光电压有显著的提高 ,是一种制备TiO2An improved method was used to prepare mercurochrome-sensitized TiO_2 photoelectrode. The transient photocurrent of the electrode at different bias and I-V curves of the photochemical cell with the electrode were measured. The results showed that the short photocurrent on the novel electrode increased by 70% and the open voltage increased by 17% compared to that on the electrode prepared by conventional method.
