A review of the features and applications of ZIF-8 and its derivatives for separating CO2 and isomers of C3- and C4- hydrocarbons

Metal organic framework (MOF) membranes have gained more attentions due to their abilities in various applications gas and liquid separations. The majority of works are related Zeolite imidazolate frameworks-8 (ZIF-8). This is often attributed its high stability, easy synthesis, good separation. They a significant interest scientists the aptitude be utilized other separations applications. Indeed, investigation literatures revealed that ZIF-8 derivatives substantial attention properties as large specific surface area, “gate opening” mechanism, etc …, which makes them special adsorption/membrane associated aspects. based materials for carbon dioxide (CO2) adsorption C3- C4- isomers’ (propane, propylene, n-butane isobutane) separation also discussed. Statistical physics approach was applied throughout this review perfect tool discuss understand ZIF-8, especially opening pressure”. Subsequently, points present highlights purpose hydrocarbon Additionally, study considers recent advancements synthesis prospects use can help better effective features sorbent methods process. As theoretical discussions referred crucial issue, first on Zeolitic Imidazolate Framework (ZIF) membrane application, provides statistical effect nanogate pressures.
