Abstract

Various types of amine-functionalized silica/organosilica membranes have been developed due to their potentially superior CO2 separation performance. This article reviews the progress made in this field and special attention is paid to elucidating the role of amine type in CO2 separation performance within amine-functionalized silica/organosilica membranes. This review includes a systematic comparison of various organosilica membranes with either unhindered or sterically hindered amines developed in our previous studies. Herein, we thoroughly discuss the structural characterizations and CO2 adsorption/desorption properties of amine-functionalized xerogel powders and CO2 transport/separation performance across the relevant membranes. Future directions for the design and development of high-performance CO2 separation membranes are suggested, and particular attention is paid to the future of activation energies for gas permeation.
Keywords: carbon dioxide separation; organosilica membrane; amine type; sterical hindrance; activation energy for permeation carbon dioxide separation; organosilica membrane; amine type; sterical hindrance; activation energy for permeation
