Abstract
In this article, a set of novel covalent triazine frameworks (CTFs) were prepared by trimerization of 4,4',4",4"-(1,4-phenylenebis(pyridine-4,2,6-triyl))-tetrabenzonitrile in molten ZnCl2 under ionothermal conditions. The influence of several parameters such as the ZnCl2/monomer ratio and reaction temperature on the structure and porosity of the resulting frameworks was systematically examined. After a thorough characterization, their performance in H-2 and CO2 adsorption as well as their selectivity of CO2 over N-2 was assessed. Notably, the CTF obtained using 20 molar equiv of ZnCl2 at a reaction temperature of 400 degrees C (CTF-20-400) exhibits an excellent CO2 adsorption capacity of 3.48 mmol/g at 1 bar and 273 K as well as a significantly high H-2 uptake of 1.5 wt % at 1 bar and 77 K. These values belong to the top levels for all the CTFs measured under identical conditions to date. In addition, the obtained CTFs also present a relatively high CO2/N-2 selectivity (up to 36 at 298 K); making them promising adsorbents for gas sorption and separation.
