Highly energy- and time-efficient synthesis of porous triazine-based framework: microwave-enhanced ionothermal polymerization and hydrogen uptake

Abstract

A covalent triazine-based framework (CTF) was synthesized by using a novel microwave (MW)-enhanced high-temperature ionothermal polymerization method. Amorphous CTF samples with high surface areas (up to 2390 m2 g−1) and high hydrogen adsorption capacities (up to 1.78 wt% at 1 bar and 77 K) could be easily obtained in tens of minutes by using such a MW-enhanced ionothermal method.
