摘要

具有大孔/介孔和微孔通道的分层多孔沸石因其比传统沸石更好的催化性能而备受关注。在这里，我们首次设计出了一种带有可水解基团的模板，可实现 pH 值的原位调节。利用这种新型模板，一步合成了具有富铝壳的核壳分层多孔 ZSM-5 沸石，与传统微孔沸石相比，这种沸石在大分子催化方面表现出更好的催化活性和选择性。

A core–shell hierarchically porous ZSM-5 zeolite with an Al-rich shell synthesized by using hydrolysable templates

Hierarchically porous zeolites with both macroporous/mesoporous and microporous channels have received significant attention due to their better catalytic performance than that of conventional zeolites. Here, for the first time, a template with hydrolysable groups that can achieve in-situ regulation of the pH value has been designed. Employing this novel template, core–shell hierarchically porous ZSM-5 zeolites with Al-rich shells were one-step synthesized, which exhibit better catalytic activity and selectivity than conventional microporous zeolites in bulky-molecule catalysis.
