Microporous materials have important potential applications for many fields of science, including gas storage, heterogeneous catalysis and chemical separations. Examples of microporous networked materials include metal organic frameworks (MOFs), " covalent organic frameworks (COFs), zeolites and microporous organic polymers (MOPs). ...

The presence of water vapour will define which materials can be used based on their hydrolytic stability. As an example metal-organic frameworks (MOFs) and covalent organic framework (COFs) are crystalline microporous materials which can exhibit exceptionally high surface areas and gas sorption capacities and, as such, have been proposed as potential materials for CCS. However, some of these materials can be unstable in the presence of moisture. The IRMOF series and the more recently produced COF materials are particularly unstable (e.g., loss of porosity at room temperature in air). Clearly, materials of this type would be unsuitable for CCS application. If such materials are to be used, more stable types are required for example, one class of MOF known as zeolitic imidazole frameworks (ZIFs) are reported to have greatly improved hydrolytic stability. 

The microwave enhanced synthesis of magnetic porous carbonaceous polymeric materials CTF/Fe203 composite (CTF = covalent triazine based framework) has been given Zhang et al. [17]. The synthesized composite finds great application in the fast separation of organic dyes from aqueous solutions.
