Polybenzimidazole (PBI)/zeolitic imidazolate frameworks (ZIF-8) mixed matrix membranes for pervaporation dehydration of alcohols

Pervaporation and membrane reactor performance of polyimide based mixed matrix membranes containing MOF HKUST-1

“…The same behavior was observed using ZIF-8/PDMS MMM for water/n-butanol mixtures (Bai et al, 2013). This MOF has also been used for the separation of water/ethanol using polybenzimidazole (PBI) (Shi et al, 2012) and polyimide Matrimid s 5218 (Kudasheva et al, 2014) as polymeric matrices, increasing both flux and the water/ethanol separation factor in comparison with the corresponding pure polymers. In addition, micro/mesoporous composite structures containing ZIF-8, i.e.…”

Thermal stability of ZIF-8 under oxidative and inert environments: A practical perspective on using ZIF-8 as a catalyst support

“…Also known as porous coordination polymers, these materials consist of infinite crystal lattices that feature metal-ion vertices and organic bridging ligands [1][2][3][4][5][6][7]. Recently, MOFs have been shown to have potential applications in drug delivery [8,9] and dehydration processes [10,11]. Zeolitic imidazolate frameworks (ZIFs) are a subclass of metal-organic frameworks composed of tetrahedrally coordinated metal ions connected by organic imidazole ligands.…”

Surface-etched halloysite nanotubes in mixed matrix membranes for efficient gas separation

“…carbon nanotubes, metal-organic frameworks, zeolites, silica, metal oxides and graphitic nanosheets) in polymer matrix is a hybrid system synergistically combining the processing versatility of polymers and the separation characteristics of fillers, showing promising separation performance [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. However, the commercial use of MMMs for gas separation has been constrained by the cost of fillers as the synthesis of these nanoparticles including nanotubes, metal organic frameworks (MOFs), silica, zeolite or graphene is time-consuming and costly.…”
