Porous Framework Materials for Gas Separation and Catalysis

Abstract

Separation of two molecules is always challenging and researchers have come up with novel techniques to achieve these targets. Introduction of porous materials generates a new research topic for such applications. Development of new porous materials as well as modifying the existing ones are the hallmarks of the porous fields. The porous materials are associated with a number of unique properties like high surface area, tunable porosity, high thermal and chemical stability etc. which make them the desired candidate for a diverse range of applications. They are applied for gas separation/storage, catalysis, optics, batteries and supercapacitors etc. Mainly two distinct classes of porous materials exist, metal-based and organic. Zeolites, metal organic frameworks (MOFs), metal organic cages, porous metal oxides belong to this class, whereas porous organic frameworks (POFs), covalent organic frameworks (COFs), organic cages, porous carbon, hydrogen-bonded organic frameworks (HOFs) etc. are the organic porous materials. In this regard, we have systematically studied the synthesis and characterization of MOF, POF, COF and porous carbon. They have been utilized for gas sorption (noble gas) and catalysis (organic and electrocatalysis).
