摘要:

硅锗分子筛因其超大的孔道结构, 在大分子催化反应领域具有潜在的应用前景. 硅锗分子筛骨架的富锗双四元环结构单元的不稳定性虽然限制了它们的实际应用, 但却为结构后处理修饰以构建新晶体结构分子筛提供了可能. 本文介绍了硅锗分子筛结构稳固、 结构可控调变和催化应用3个方面的研究进展, 并展望了其未来的发展方向和挑战.

Abstract:

Germanosilicates with (extra)-large pores have shown significant potential in the bulky molecules-involved catalytic reactions. However, the Ge―O bonds are easily hydrolyzed even in humid environment and induced structural collapse, which restricts the practical application of germanosilicates. However, the weak Ge―O bonds also endow germanosilicates structural modifiable properties for possible construction of novel zeolite frameworks by partial or full removing framework Ge atoms to induce structural deconstruction and reconstruction. The review summarizes recent progresses achieved in field of germanosilicates, including structural stabilization of germanosilicates, structural modification of germanosilicates, and their promising catalytic applications. Last but not the least, future challenges in the field of germanosilicates are also proposed.

Key words: Germanosilicate, Structural stabilization, Structural modification, Novel zeolites, Catalysis
