以钛酸四正丁酯为钛源,柠檬酸为辅助剂,无水乙醇为溶剂,采用溶剂热法制备了单分散锐钛矿型TiO2亚微米级球,并研究了其对罗丹明的光催化降解性能。此外,以制备的TiO2亚微米级球为前驱体,利用其与浓碱的水热反应,制备了具有等级结构的钛酸盐纳米线球和纳米管球。
Uniform anatase TiO2 sub-microspheres composed of nanoparticles were prepared via a citric acid as assisted hydrolysis of tetra-n-butyl titanate in ethanol under solvothermal conditions. The photocatalytic activity of the as-prepared TiO2 spheres was evaluated by the photodegradation of RhB. The as-prepared TiO2 spheres were treated with concentrated alkali hydroxide solution to transform nanoparticles into nanotubes, leading to the formation of hierarchically structured TiO2 spheres consisting of nanotubes.
