摘　　要：利用水热合成法制备了一种新型硅酸锡微孔化合物(Microporous stannosilicates),通过XRD,SEM,29Si MAS NMR,119Sn MAS NMR,IR和TG等测试手段对该硅酸锡微孔化合物进行了表征.结果表明,该硅酸锡微孔化合物中的Sn物种为六配位形式,而此化合物与硅锆矿石(Litvinskite)具有相同的拓扑结构.A novel microporous framework stannosilicate was hydrothermally synthesized and characterized by XRD,SEM,29 Si MAS NMR,119 Sn MAS NMR,IR and TG techniques.The results show that sample with sixcoordinative Sn atoms has the same topology with zirconosilicate mineral litvinskite.XRD peaks indicate that the sample has the same topology with zirconosilicate mineral litvinskite;SEM images exhibit that the sample has similar morphology with size of 10—50μm;NMR results show that the sample has six-coordinative Sn atoms;IR spectrum indicates that there two bands at 615 and 544 cm-1 associated with Sn—O stretching freqencies;TGA curve gives mass loss at 9.2%in the range of 35—800℃,assigned to adsorbed water at 35—100℃and framework water at 100—800℃,respectively.
