Nitride Zeolites from Ammonothermal Synthesis.

ABSTRACT: Oxide zeolites are synthesized from aqueous solutions in an established way employing hydrothermal synthesis. Transferring this approach to nitride zeolites requires a solvent providing nitrogen for which ammonia has proven to be particularly suitable. We present the successful ammonothermal synthesis of the (oxo)nitridosilicate compounds Ce₃[Si₆N₁₁], Li₂RE₄[Si₄N₈]O₃ (RE=La, Ce) and K_1.25Ce_7.75[Si₁₁N₂₁O₂]O_0.75. Within this procedure, the usage of supercritical ammonia as a solvent as well as the utilization of the mineralizers NaN₃, Li₃N and KN₃, respectively, allowed the targeted synthesis of large single
