Abstract

Abstract ɛ-Keggin-based mixed metal oxide (ɛ-MoMO) comprises a network arrangement based on an ɛ-Keggin {Mo12O40} unit and a {MO6} octahedral, forming a framework structure containing cage and channel textures such as an Faujasite (FAU)-type zeolite. In this study, we successfully synthesized 3 novel ɛ-MoMOs, namely ɛ-MoMgO, ɛ-MoYO, and ɛ-MoInO, and their physicochemical properties were investigated. All these materials showed a microporosity to adsorb CO2 of up to 33% to 42% in their crystallographically expected microporous capacity.
