| 摘 要： | 以不同方法制备棒状、球状和花状3种形貌的TiO_2纳米粒子,采用X粉末衍射、扫描电子显微镜、荧光光谱和紫外-可见漫反射等对TiO_2纳米粒子进行结构及形貌分析。以亚甲基蓝为降解模型,分别在紫外光与可见光条件下对TiO_2纳米粒子进行光催化性能研究,分析TiO_2的形貌结构影响光催化性能的机理。结果表明,花状TiO_2纳米粒子光催化性能最好,其中高能晶面与微观形貌尺寸对TiO_2光催化性能具有重要影响。

| Abstract: | Aseries of TiO2 with rod,spherical and flower morphologies weresynthesized successfully.The as-prepared catalysts were characterized by XRD、SEM、UV-VIS.Methylene blue(ME) was used as the aimed degradation material to observe the performance of photocatalysis under ultraviolet and visible light.The mechanism of the effect of morphology and structure of TiO2 on photocatalytic performance was analyzed.The results showed:photocatalytic effect of Flower-like(P25) was the best.The high energy facets and theoretic of morphology have an important influence on the photocatalytic of TiO2. |
