Thermodynamics of metal-organic frameworks

摘要: Although there have been extensive studies over the past decade in synthesis and application of metal-organic frameworks (MOFs), investigation their thermodynamic stability energetics guest–host interactions has much more limited. This review summarizes recent progress experimental (calorimetric) determination thermodynamics MOF materials. The enthalpies MOFs relative to dense phase assemblages suggest only modest metastability, with a general increase enthalpy increasing molar volume, which becomes less pronounced at higher porosity. energy landscape nanoporous materials (inorganic hybrid) consists pair parallel patterns within fairly narrow range metastability 5–30 kJ per mole tetrahedra zeolites mesoporous silicas or metal MOFs. Thus strong instability does not seem limit framework formation. There are chemisorption for small molecule–MOF defined chemical binding centers other specific locations. Coexistence surface confinement can lead stronger interactions. - Graphical abstract: Energy inorganic hybrid porous Highlights: • Thermochemical data on various structures were experimentally determined. moderately unstable relativemore » assemblage.
