摘　　要：利用浸渍提拉法制备了纳米TiO2 多孔膜 采用紫外光源 ,以 [Fe(CN ) 6 ]3- / [Fe(CN) 6 ]4 - 溶液为电解质 ,分别以两种染料敏化纳米TiO2 膜为光阳极制成了一种新型的紫外光电池 ,探讨了该电池的伏安特性曲线 电池最大电压为 0 .36mV ,最大电流密度为 0 .0 2 μA/cm2 。Nanoporous titanium dioxide(TiO 2) films was prepared by sol gel method. For the first time, a novel device based on conventional dye sensitized ultraviolet electric cell was obtained by using anthocyanins and coumarin as the dye and 3- / 4- as electrolytes. The I V characteristic of the cell, which had 0.36 mV as its maximum voltage and 0.02 μA/cm 2 as its maximum current were described. The mechanism of photoemission was also investigated.
