二氧化钛纳米片组装结构的制备及其在酸性条件下对亚甲基蓝的高活性催化
natase TiO2 microspheres assembled from nanoparticles with high photocatalysis of methylene blue under acidic conditions
在酸性水热条件下，利用四氟化钛为反应源通过嵌段聚合物P123和柠檬酸的辅助作用制备出具有锐钛矿相的二氧化钛纳米片的球形组装结构。光催化研究表明该二氧化钛组装结构在pH为3-4的条件下具有很好的光催化降解亚甲基蓝的性能，显示出良好的应用前景。
natase titania flower-like microspheres assembled by nanoparticles were fabricated via hydrothermal hydrolysis of TiF4 with the assistance of tri-block copolymer P123 and citric acid monohydrate at pH 1.5-2.0. The structure, morphology, specific surface area, pore size distribution, optical and photochemical properties of the microspheres were investigated. It was found that the calcined flower-like microspheres were composed of nanostructures with some high-index planes and they showed higher photodegradation efficiency than Degussa P25 to decompose methylene blue (MB) at pH 3-4 despite having a smaller specific area (about one seventh) comparing with Degussa P25.
