We report a method to efficiently produce all-silica hollow zeolites by leaching their parent crystals in sodium aluminate and hydrochloric acid solutions successively. The extra-framework aluminum species resulted from the dissolution of sodium aluminate can protect the crystal rim from damaging, and are subsequently eliminated by acid wash.

选择性脱金属合成全硅空心沸石

我们报告了一种通过依次在铝酸钠和盐酸溶液中浸出其母体晶体来有效生产全硅空心沸石的方法。铝酸钠溶解产生的额外骨架的铝物种可以保护晶体边缘免于损坏,随后通过酸洗消除。
