Organotemplate-free hydrothermal synthesis of an aluminophosphate molecular sieve with AEN zeotype topology and properties of its derivatives

Abstract

A facile organotemplate-free route has been developed to synthesize an aluminophosphate molecular sieve in an alkali metal-containing system under hydrothermal conditions. The as-prepared JU93 possesses AEN zeotype topology with small 8-ring pores, and its derivatives show ion conductivity and adsorption selectivity of CO2 over CH4.
