银和钯修饰二氧化锰/二氧化钛光电极光催化性能研究
发布时间：2020-12-09 02:35
直接利用太阳能为光源的TiO2光催化技术被认为是21世纪最具应用前景的环境治理技术之一,它既解决了能源危机的困扰,又满足了污染防治的迫切需要。与薄膜电极相比,阳极氧化法制备的TiO2纳米管阵列（TiO2 NTs）因具有较高的比表面积、独特的尺寸效应和良好的光吸收性能,在太阳能转换、光解水制氢和污染物去除领域得到了广泛关注。然而,TiO2对可见光利用效率较低,不能有效利用太阳能。本论文在制备高度有序的TiO2 NTs基础上,通过MnOx改性获得具有可见光响应的复合TiO2光电极,并对其物理化学结构、光电化学性能和光电催化学性能进行了系统研究,以期为二氧化钛光催化氧化技术处理废水中难降解有机物的实用化提供依据。为解决粉末态催化剂不易回收、难重复使用的问题,本文采用电化学阳极氧化法以钛片为基底原位制备TiO2 NTs,研究四种不同类型的电解质溶液（NH4）2SO4<...
