AbstractBy means of vacuum-assisted impregnation,cobalt nitrate was dipped into TiO2 nanotubes and then calcinated at 400 ℃. Thus,the photo-catalyst of Co3O4 nanoparticles embedded in TiO2 nanotubes( TNT) was obtained. The material was characterized by means of X
Other Abstract采用真空辅助浸渍法,将硝酸钴浸入TiO2纳米管内,再经400℃焙烧得到Co3O4纳米粒子内嵌于TiO2纳米管的光催化剂.通过X射线衍射、透射电子显微镜、X射线光电子能谱、紫外-可见光谱等测试手段对材料进行表征,并在可见光照射下,通过光解水制氢评估材料的催化性能.实验结果显示,高度分散的Co3O4内嵌于TiO2纳米管内,粒径为3-5 nm.与Co3O4负载于TiO2纳米管外的催化剂相比,管内的Co3O4与TiO2纳米管之间的相互作用增大,其可见光吸收明显增强,可见光分解水制氢性能显著提高.
