Synthesis of fluidized CO2 sorbents based on diamine coordinated to metal- organic frameworks by direct conversion of metal oxides supported on mesoporous silica

Abstract

A general and efficient method for shaping MOFs into fluidized forms has been developed by direct conversion of metal oxides supported on fluidized meso-porous silica. The resulting fluidized MOF hybrid materials containing diamines coordinated at the open metal sites have been studied as CO2 solid sorbents from post-combustion flue gas showing similar performance than their bulk counterparts. These new fluidized MOF hybrid materials can be used for other applications involving fluidized bed reactor configurations, in which MOFs have never been considered.
