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.
