中文摘要：
以钛酸正丁酯（TBOT）为钛源、发烟硅胶为硅源、四甲基氢氧化铵（TMAOH）为模板剂，采用一步法直接水热合成了CDO（Cylindrically Double Saw-Edged Zeolite One）晶体结构的含钛分子筛Ti-CDS-1．用粉末X射线衍射、电子扫描、紫外可见漫反射光谱、傅立叶变换红外光谱等手段对所合成的样品进行了表征．结果表明，Ti-CDS-1维持原来全硅分子筛的片状晶体外形；原料中钛原子大部分嵌入到CDS-1分子筛骨架，少量钛在分子筛表面形成八面体非骨架钛物种，这部分骨架外钛可以用酸处理选择性去除。
英文摘要：
A novel titanosilicate with the CDO （Cylindrically Double Saw-Edged Zeolite One） structure, Ti-CDS-1, has been hydrothermally synthesized by using tetrabutylorthotitanate （TBOT） as a Ti source, fumed silica as a Si source, and tetramethylammonium hydroxide （TMAOH） as a template. The samples were characterized by various techniques such as XRD, SEM, UV-visible and FT-IR spectroscopies. Ti-CDS-1 showed a morphology of thin plate crystals comparable to siliceous CDS-1. Ti-CDS-1 contained Ti species mainly in the framework in addition to a small part of octahedral extraframework Ti on exterior crystal surfaces. The extraframework Ti species could be removed selectively by an acid treatment.
