Abstract A series of molybdenum titanium oxides (TiO 2 –MoO 3 ) were successfully prepared by hydrothermal method using P25 and TiCl 4 as titanium resource, respectively. The particle size and morphology of molybdenum titanium oxides was controlled by adding thiourea as surfactant. The catalytic activity of the obtained materials was evaluated by degradation of NO under simulated solar light irradiation. The results showed that the morphology of obtained molybdenum titanium oxide can be significantly controlled by adding thiourea. And the samples with novel curly petal-like layered structure exhibited superior catalytic activity. Trapping experiments revealed that ·O 2 − was the main active specie in the catalytic system. Also the catalyst had superior stability and reusability. Graphic Abstract

钼钛氧化物的形态控制及其增强的NO去除性能

摘要 分别以P25 和TiCl 4 为钛资源，采用水热法成功制备了一系列钼钛氧化物(TiO 2 -MoO 3 )。通过添加硫脲作为表面活性剂来控制钼钛氧化物的粒径和形貌。通过模拟太阳光照射下NO的降解来评价所得材料的催化活性。结果表明，加入硫脲可以显着控制所得钼钛氧化物的形貌。具有新型卷曲花瓣状层状结构的样品表现出优异的催化活性。捕集实验表明·O 2 - 是催化体系中的主要活性物质。该催化剂还具有优异的稳定性和可重复使用性。图形摘要
