摘　　要：采用水热晶化法，以四乙基氢氧化铵（ＴＥＡＯＨ）为模板剂合成了具有沸石孔道结构的钛酸镓。考察了该分子筛的晶化过程，反应体系的ｐＨ值是影响分子筛生成质量的主要因素。产物的结构用Ｘ射线衍射、红外光谱、紫外光谱、透射电镜、热分析等进行了表征。Gallium titanate molecualr sieves was synthesized hydrothermally with the template TEAOH. The effects of the reaction system on the crystallization were investigated. The results indicate that the pH value is the main factor during the syntheses process. The structural chatacterization was made by using the methods of XRD, IR, UV-Vis, TEM and DTA.
