Germanosilicate UTL and its rich chemistry of solid-statetransformations towards IPC-2 (OKO) zeolite

Popis výsledku v původním jazyce

The unique features of the germanosilicate zeolite possessing the UTL framework topology offer various post-synthetic modifications such as top-down?, inverse sigma? or solid-state transformations. The presented work describes several different syntheticroutes generating the IPC-2 type zeolite (OKO topology) utilizing UTL as the parent material. In total, five approaches were investigated which exhibit this topological transformation from germanosilicate UTL to OKO type material: (1) alkoxysilylation of the layered precursor (IPC-1P) formed by hydrolysis of UTL; (2) direct conversion of UTL by treatment in 7?12 M hydrochloric acid; (3) direct transformation under mild conditions of water and ammonium nitrate solution on Al- and B-UTL; (4) repeated calcinations of boron-containing UTL; (5) using organic solutions as self-stabilization agents. Resulting materials were examined by powder XRD, nitrogen sorption, SEM and EDX. Briefly, all the materials possessed the same OKO topology but h
