Superhydrophobic MOFs with enhanced catalytic activity for chemical fixation of CO2

Abstract

A general approach to prepare superhydrophobic MOFs (denoted as MOFs-CF₃) through a post-decorating strategy for highly efficient chemical fixation of CO₂ was demonstrated. The enhanced catalytic activity of MOFs-CF₃ is attributed to a synergistic effect between the Lewis acid sites of MOFs and modification of the electron-withdrawing trifluoromethyl group, which resulted in a high CO₂ enrichment capacity. The possible mechanism of cycloaddition catalyzed by the MOFs-CF₃ catalyst was also proposed.
