Synthesis and characterization of porous material and their application in gas storage

Abstract

Covalent organic frameworks (COFs) are an emerging class of porous covalent organic structures whose backbone is composed of light elements (B, C, N, O, Si) and linked by robust covalent bonds to endow such material with desirable properties, i.e., inherent porosity, well defined pore aperture, ordered channel structure, large surface area, high stability, and multi dimension. As expected, the above-mentioned properties of COFs broaden the applications of this class of materials in various fields such as gas storage and separation, catalysis, optoelectronics, sensing, small molecules adsorption, and drug delivery. In this thesis, I have synthesized different types of COFs and highlighted their applications in gas storage. This thesis introduces important research progress of covalent organic frameworks (COFs) and their synthesis and applications in the field of gas storage. In this project work, we are trying to synthesize four different COFs by using imine condensation and changing only the amine linker keeping the aldehyde linker fixed. We found that TPT-CHO - TTBA based COF (TPT-COF-3) has a surface area of 3529.81 m2/gm, TPT-CHO – TTTA based COF (TPT-COF-2) has a surface area of 2128.83m2/gm, TPT-CHO – TAPT based COF (TPT-COF-1) has surface area 1395.43 m2g-1 and TPT-CHO – TAPB (TPT-COF-4) has a surface area of 304 m2/gm.
