Benzimidazole-based hyper-cross-linked poly(ionic liquid)s for efficient CO2 capture and conversion

Porous materials with high Brunauer-Emmett-Teller (BET) surface area (SBET) and abundant ionic active sites facilitate efficient CO2 capture and conversion. Herein, a kind of novel benzimidazole-based hyper-cross-linked poly(ionic liquid)s (HPILs) were developed via the hyper-cross-linking strategy and the as-prepared HPILs possessed high SBET (485–780 m2/g), plentiful micro/mesoporosity, and abundant ionic active sites. The HPILs showed...
