The first zeolitic pure germanate built up from the four-membered ring — CCUT-9 showing high surface area

CCUT-9, the first zeolitic pure germanate built up from the four membered ring, has been hydrothermally synthesized by the co-templated method of alkali and organic amine. The structural determination gives rise to the neutral framework of CCUT-9 with solvent free void of 1085 Å3 (17.39%). Furthermore, the N2 isothermal adsorption shows that CCUT-9 possesses a Langmuir surface area of 586 m2/g (lower P/P0), corresponding to a BET surface area of 811 m2/g (higher P/P0).
