SnBu_4 could react with superficial hydroxy group of Pt/HY molecular sieve,to result selective and quantitative grafting of SnBu_3 fragments onto surface of molecular sieve supercages without deteriorating crystalline structure of the latter.

• 研究结果表明,SnBu4与Pt/HY分子筛表面羟基可以定量、有选择性地进行化学反应,将确定数目的SnBu3碎片接枝在分子筛的超笼中。
