A green solvothermal synthesis approach employing water as a hollowing controller and diethylenetriamine as both crystal growth stabilizer and N dopant source to the preparation of hierarchical N-doped TiO(2) hollow microspheres comprised of nanothorns with exposed anatase {101} facets is established. The superstructured TiO(2) shows excellent photocatalytic activities in degrading dyes under visible light irradiation.
采用水作为中空控制器，乙二胺作为晶体生长稳定剂和 N 掺杂源的绿色溶剂热合成方法，制备了由暴露锐钛矿{101}面的纳米刺的纳米棒组成的具有分级结构的 N 掺杂 TiO2 空心微球。这种超结构 TiO2 在可见光照射下降解染料时表现出优异的光催化活性。
