Metal–organic framework (MOF)-, covalent-organic framework (COF)-, and porous-organic polymers (POP)-catalyzed selective C–H bond activation and functionalization reactions

Chemical Society Reviews, Journal Year: 2022, Volume and Issue: 51(18), P. 7810 - 7882

Published: Jan. 1, 2022

Although C–H functionalization is one of the simplest reactions, it requires use highly active and selective catalysts. Recently, C–H-active transformations using porous materials such as crystalline metal-organic frameworks (MOFs) covalent-organic (COFs) well amorphous porous-organic polymers (POPs) new emerging heterogeneous catalysts have attracted significant attention due to their promising activity potential material tunability. These solids offer exceptional structural uniformity, facile tunability permanent porosity. In addition, tuning catalytic selectivity these can be achieved through engineering site microenvironments, metal node substitution, linker changes, node/linker functionalization, pore modification. The present review provides an overview current state art on MOFs, COFs POPs advanced for various bond activation providing details about chemo-, regio-, stereo-selectivity control, comparing performance with that other catalysts, triggering additional research by showing limitations challenges in this area, a perspective future developments.

Atomically synergistic Zn-Cr catalyst for iso-stoichiometric co-conversion of ethane and CO2 to ethylene and CO

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 30, 2024

Abstract Developing atomically synergistic bifunctional catalysts relies on the creation of colocalized active atoms to facilitate distinct elementary steps in catalytic cycles. Herein, we show that atomically-synergistic binuclear-site catalyst (ABC) consisting $${{{{{\rm{Zn}}}}}}^{\delta+}$$ Zn δ + -O-Cr 6+ zeolite SSZ-13 displays unique properties for iso-stoichiometric co-conversion ethane and CO 2 . Ethylene selectivity utilization converted can reach 100 % 99.0% under 500 °C at conversion 9.6%, respectively. In-situ/ex-situ spectroscopic studies DFT calculations reveal atomic synergies between acidic Zn redox Cr sites. ( $$0 \, < \delta 2$$ 0 < 2 ) sites β-C-H bond cleavage formation Zn-H δ - hydride, thereby enhanced basicity promotes adsorption/activation prevents C-C scission. The site accelerates dissociation by replenishing lattice oxygen facilitates H O formation/desorption. This study presents advantages ABC concept, paving way rational design novel advanced catalysts.
