Abstract
The present disclosure is directed to large-pore germanosilicate compositions designated CIT-13/OH and CIT-14/IST, the two large-pore germanosilicate each having a three-dimensional framework with 10- and 14-membered ring channels and 8- and 12-membered ring channels, respectively. The disclosure also sets forth methods for converting the former to the latter under conditions consistent with an inverse sigma transformation. Uses of the large-pore germanosilicate compositions are also disclosed.
