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.

关键词: 水热合成; 硅酸锡; 微孔化合物; 硅锆矿石

Abstract:

A novel microporous framework stannosilicate was hydrothermally synthesized and characterized by XRD, SEM, ²⁹Si MAS NMR, ¹¹⁹Sn MAS NMR, IR and TG techniques. The results show that sample with six-coordinative 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—50 μm; 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.
