Enhanced carbon dioxide uptake by metalloporphyrin-based microporous covalent triazine framework

Abstract

A class of metal functional microporous covalent triazine frameworks was prepared using a metalloporphyrin as a single building block, which is insoluble in common organic solvents and water, and can remain stable up to 500 °C under nitrogen atmosphere. According to the nitrogen physisorption isotherms, the highest Brunauer–Emmett–Teller specific surface area up to 1510 m2 g−1 was obtained for the new polymer framework with a pore volume of 2.674 cm3 g−1. The polymer framework displays excellent carbon dioxide uptake capacity (up to 13.9 wt%) at 273 K and 1 bar, which is influenced significantly by the porosity of the frameworks and functional activated sites in the skeletons.
