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.
