Zeolitic imidazolate framework monoliths with high mesoporosity and effective adsorption of toluene from aqueous solution

Abstract

A monolithic mesoMOF based on ZIF-8 is created as an efficient adsorbent for toluene from aqueous solution.

Metal–organic framework gels and monoliths

“…99 Monolithic MOFs with large surface areas, tuneable wettabilities and good water resistance have been shown to play an important role in oil-water separations. 100 In a recent study, a superhydrophobic (water contact angle of above 170 ), waterstable MOF containing Cu 2+ and hexauorinated dicarboxylate linkers was prepared. Aer coating on a porous support, the monolithic MOF lm exhibits excellent oil absorption capacities and reusability, during the separation of hexadecane, bio-diesel, toluene and crude oil from water ( Fig.…”
