High performance ZIF-8/PBI nano-composite membranes for high temperature hydrogen separation consisting of carbon monoxide and water vapor

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

“…Zeolite imidazole framework-8 (ZIF-8) has attracted extensive research interest because of its simple synthesis and various formulations [14,[16][17][18][19][20][21][22], its outstanding thermal and chemical stability [12,23,24], and its potential applications in catalysis [25][26][27][28] and gas separation [13,19,20,29,30]. In many industrial processes, harsh conditions such as high temperatures, high pressures, and the presence of oxidants are required.…”

The impact of water vapor on CO2 separation performance of mixed matrix membranes

“…The separation of CO 2 from large emission sources such as power, iron and cement plants and its subsequent storage (i.e., carbon capture and storage) would reduce the total CO 2 emissions [1,2]. Applications for clean energy production involving hydrogen recovery [3,4], natural gas sweetening [5,6] and methane recovery from biogas [7] also require the separation of carbon dioxide and have received considerable attention in recent years. Polymeric membrane-based separation technology is an attractive approach to such gas/vapor separation due to its ease of operation, energy efficiency and cost-effectiveness, relative to absorption, adsorption and cryogenic distillation, and has been applied in industrial applications [2,8,9].…”

Poly(vinyl alcohol)/ZIF‐8‐NH2 mixed matrix membranes for ethanol dehydration via pervaporation

“…37,38 Zeolitic imidazolate framework (ZIF) material, as one promising nanofiller in the membrane matrix, is a subfamily of metal organic frameworks, and possesses tunable structures and favorable affinity with the polymer matrix as compared with most other traditional inorganic particles with rigid frameworks. 39,40 It is, and therefore, considered as one promising nanofiller to be incorporated into the polymer matrix, 41,42 such as polymethylphenylsioxane, 18 polydimethylsiloxane (PDMS), 43 chitosan, 44 PVA, 45 polybenzimidazole, 46,47 polyether-blockamide, 48 polysulfone (PS), 49,50 polyimide, 51,52 and polymerizable room temperature ionic liquid. 53 The incorporation of ZIF can significantly improve the separation performance and mechanical properties of the membrane.…”
