中文摘要: 分析了一种独特的、基于过氧钒酸缓慢且可控的还原和转化的方法，用于在FTO基底制备纳米孔钒酸铋（BiVO4）光阳极。结果表明，所制备的BiVO4光阳极具有单斜白钨矿结构，以Ag/AgCl电极为参比电极，在0.6 V的偏压下可获得高达1.10 mA/cm2的光电流密度。将其与铂修饰的多晶硅电池片光阴极复合构建光催化废水燃料电池。结果表明，其具有优越的降解盐酸四环素性能和良好的稳定性，在4 h内可将盐酸四环素去除70.8%，而且系统在降解盐酸四环素的同时对外稳定产电。

Abstract:A unique,slow and controllable method based on the reduction and transformation of peroxovanadate was reported for the preparation of nanoporous BiVO4 photoanode on the FTO substrate.The results showed that the prepared BiVO4 photoanode possessed a single monocline scheelite structure,and exhibited an optimal water splitting photocurrent density of 1.10 mA/cm2 at 0.6 V vs Ag/AgCl.With Pt modified silicon photocathode a photocatalytic wastewater fuel cell was constructed,the results show that the system demonstrated superior performance and good stability for tetracycline hydrochloride degradation was removed.And 70.8% of tetracycline hydrochloride was removed within four hours.Meanwhile in the degradation course of tetracycline hydrochloride external stable electricity production was achieved.
