介绍了新型复合电极的制备方法、其双功能特性以及在提高水中有机污染物 (如苯胺 )降解速度所起的作用 ,并对其作用机制进行了讨论 .实验结果表明 ,由空气电极和 Ti O2 光催化剂组成的复合电极 ,当其工作电位控制在 0 .0 5 V(vs.SCE)左右时 ,既具有良好的光电效应 ,又具有以较高效率合成 H2 O2 的特性 ,使溶液中的有机分子获得来自光催化氧化与光化学氧化两方面的联合降解作用 ,从而显著地提高了有机分子的氧化降解速度 The preparation method of novel composite electrode, its bifunctional properties and its role in improving the degradation rate of organic pollutants (such as aniline) in water are discussed, and its mechanism of action is also discussed.The experimental results show that the air electrode and Ti O2 When the working potential of the composite electrode composed of photocatalyst is controlled at about 0. 05 V (vs.SCE), it has both good photoelectric effect and high efficiency of synthesizing H2 O2, so that the organic The molecules are derived from the combined degradation of both photocatalytic and photochemical oxidation, thereby significantly increasing the rate of oxidative degradation of organic molecules
