Charged Covalent Triazine Frameworks for CO2 Capture and Conversion

摘要: The quest for the development of new porous materials addressing both CO2 capture from various sources and its conversion into useful products is a very active research area also critical in order to develop more sustainable environmentally-friendly society. Here, we present first charged covalent triazine framework (cCTF) prepared by simply heating nitrile functionalized dicationic viologen derivatives under ionothermal reaction conditions using ZnCl2 as solvent trimerization catalyst. It has been demonstrated that surface area, pore volume/size cCTFs can be controlled varying synthesis temperature content. Specifically, increasing led increase mesopore content facilitated formation hierarchical porosity, which ensure efficient mass transport within materials. resulting showed high specific areas up 1247 m2 g–1, physicochemical stability.
