Abstract

The present disclosure is directed to novel germanosilicate compositions and methods of producing the same. In particular, this disclosure describes new silica-rich compositions of the germanosilicate designated CIT-13, with and without added metal oxides. The disclosure also describes methods of preparing and using these new germanosilicate compositions as well as the compositions themselves.
