中文摘要： 微纳分级结构纳米分子筛材料是国际大分子催化领域研究的热点。无模板自发自组装技术，以纳米材料为结构单元，不仅能有效地构筑微/纳米尺度上的分级结构，而且合成更简便、成本效率更合算，为材料规模化制备提供了基础。但是，自组装材料的低稳定性是制约其应用的瓶颈问题。如何增强纳米微晶的界面相互作用是提高稳定性的关键。本项目将研究：1，纳米分子筛微纳米分级结构的自发自组装合成技术；2，微纳米分级结构的自组装机理和结构单元纳米微晶相互作用机制；3，微纳分级结构纳米分子筛的稳定性及大分子催化裂化应用。

英文摘要： Hierarchical structured zeolites is already known as one of most important catalysts in bulky molecular catalysis, have been a hot research topic.Spontaneous self-assembly without templating provides a simple and low-cost method for large-scale preparation of ensembles of nano-unites with hierarchical micro/nano structure.However, improvement of stability of self-assembly materials has been extremely challenging. Enhancement of the interface interaction of nanocrystals is therefore considered as key factor of solving this bottle-neck problem in practical application of self-assembly materials. Aims of our proposal projects are as the following: Firstly, new spontaneous self-assembly and relevant nanotechnological synthetic methodology will be developed for the preparation of hierarchical structured zeolites constructed by nanocrystals; Next, for extension of synthetic methodology, the exploration of mechanism of new spontaneous self-assembly methods and interface interaction are more desired for the synthesis and application of novel hierarchical structured architectures. Finally, for extension of applications, the investigation of stability is still required for further improvement of catalytic activity in bulky molecular cracking.
