Abstract Assisted by microwave irradiation, high surface area TiO2 nano-photocatalysts were synthesized via fast hydrolysis of inorganic titanyl sulfate, followed by post-annealing treatment at 700 °C. The microwave facilitated the reaction but constrained the growth of individual TiO2 particles. Strikingly, the sulfuric acid added in the reaction system for hydrolysis control also affected the morphology of the formed TiO2 leading to a mesoporous structure. The heat treatment endowed the TiO2 nanocrystals with a comfortable ratio of anatase and rutile. The mesoporous TiO2 particles thus obtained were agglomerates of

微波合成无模板的H 2 SO 4 诱导介孔TiO 2 纳米光催化剂

摘要 在微波辐照的辅助下，无机硫酸氧钛快速水解，然后在700 ℃下退火，合成了高表面积TiO2纳米光催化剂。微波促进了反应，但限制了单个 TiO2 颗粒的生长。引人注目的是，在反应体系中加入的用于水解控制的硫酸也影响了形成的 TiO2 的形态，导致了介孔结构。热处理赋予 TiO2 纳米晶体以舒适的锐钛矿和金红石比例。由此获得的介孔 TiO2 颗粒是
