Interfacial Polymerization of Covalent Organic Frameworks for The Application of Ammonia Production

Novel supramolecular structural design, covalent organic frameworks (COFs), was determined by various exact chemical structures such as benzobisthiazole, benzene-1,3,5-tricarbaldehyde, benzene-1,4-diamine, or 2,4,6-Triformylphloroglucinol etc. derivatives. The one-pot synthesis of COFs was achieved from the monomers which was dissolved in the unmixed Brønsted acid and Brønsted base under the Schiff-base reaction system. NMR, TGA, DSC, SEM, PLM, FTIR, contact angle and X-ray scattering (SAXS/WAXS) were used to detect the relationship of effective ammonia production and intermolecular exchange reaction, in order to control the processing conditions. An overall understanding of the physical mechanism of COFs nafion film would be investigated according to the influence of the structural changes on the crystallinity as well as crystal phase morphology. Therefore, our work demonstrates a practical potential for COFs as an ammonia production platform.
