One-step solvent-free aerobic oxidation of aliphatic alcohols to esters using a tandem Sc–Ru⊂MOF catalyst

Abstract

Esters are an important class of chemicals in industry. Traditionally, ester production is a multi-step process involving the use of corrosive acids or acid derivatives (e.g. acid chloride and anhydride...

Advancements of MOFs in the Field of Propane Oxidative Dehydrogenation for Propylene Production

“…A higher conversion rate indicates that the catalyst can more effectively promote the reaction while reducing side reactions and catalyst loss. The conversion rate can be determined using methods such as colorimetry [ 77 , 78 ], gas chromatography [ 79 , 80 , 81 ], and nuclear magnetic resonance [ 82 ]. TOF [ 83 ]: TOF refers to the number of reactant molecules converted per active site on the catalyst per unit time.…”

“…Additionally, catalysts with high selectivity can provide high purity and selectivity for the target product, meeting market demands and quality standards. The selectivity of a catalyst can be evaluated by measuring the yield and selectivity for the target product using analytical methods such as gas chromatography, high-performance liquid chromatography [ 79 , 88 ], etc. It can also be studied by investigating the reaction mechanism and intermediates [ 79 , 89 , 90 , 91 ] providing a deeper understanding of selectivity.…”

Furthermore, DFT calculations [ 43 , 92 ] can predict the energy barriers and reaction activity of different reaction pathways, facilitating the theoretical prediction of catalyst selectivity and the validation of reaction mechanisms.…”

Continuous flow synthesis of PCN-222 (MOF-545) with controlled size and morphology: a sustainable approach for efficient production

“…MOFs have garnered significant scientific interest due to their regular porosity and tuneable pore size, multivariate structures with multiple metals (either mono-, bi-, or tri-metallic systems) and/or organic linkers, and conformation-ally flexible linkers and/or geometrically versatile inorganic building units. 1,2 In addition, MOFs can be functionalized (both the external surface and internal pore space) by post-synthetic modifications (PSM) to install new functionalities. Up to date, more than 100 000 different MOFs have been explored for potential applications in drug delivery, imaging, sensing, catalysis, gas (hydrogen, carbon dioxide, methane) storage and other biomedical uses, and a further half a million structures of MOFs have been hypothesized.…”
