| 摘 要： | 以四乙基氢氧化铵(TENOH)为胶溶剂和钛酸丁酯(TNB)为前驱体,采用水热法制得了一系列TiO2纳米晶.运用XRD、TEM和DLS等表征手段阐明了纳米晶粒子定向聚集-原位晶化的形成过程,探索出制备高性能粉体的温度和试剂比.研究表明,TENOH/Ti摩尔比为0.25时,则可得到分散性和成形性俱佳的二氧化钛晶体;温度对制备粉体的微观性质也有一定影响.本制备过程简便易控,在光催化水处理等领域具有很好的研究价值和潜在的应用前景.

| Abstract: | Series of nanocrystalline anatase titanium dioxide particles were prepared with titanium butoxide(TNB) in situ by hydrothermally treating amorphous titania particles peptized with different amounts of tetraethylammonium hydroxide(TENOH).X-ray diffraction(XRD) and Transmission electron microscopy(TEM) analyses were used to characterize the crystalline phase and morphology of the TiO_2 particles.The influence of the quantity of TENOH and the reaction temperature on the shape and size of the as-prepared titanium dioxide particles was mainly investigated.The as-prepared titanium dioxide particles will have the best characterization if the TENOH/Ti ratio is at a moderate value.The temperature also has an effect on the microstructure of the particles.Compared with other methods,hydrothermal process is a promising novel method for synthesis. |
