ABSTRACT A nitrogen‐doped carbon‐supported Fe‐Fe 3 C‐Fe O 4 composite (Fe‐Fe @CN) has been synthesized through a one‐step pyrolysis of an iron‐based complex (Fe@tremella‐est), in alignment with the principles surface organometallic chemistry (SOMC). The Fe@tremella‐est was straightforward chelation process using N‐containing alanine‐modified tremella (tremella‐est) as raw material. This approach enhances resulting catalyst by providing large specific area, high dispersity, and increased number Fe‐N species. These distinctive advantages confer upon @CN higher catalytic efficiency compared traditional catalysts C@CN C@CN‐550), along enhanced stability during recycling experiments. SOMC strategy may serve new framework for synthesis biomass‐derived nanocatalysts various reactions.

Abstract The acceptorless dehydrogenation reaction is a sustainable and atom‐economical methodology in organic synthesis, resulting the byproducts of only hydrogen or water. Herein, robust Co−Si/CN catalyst (derived from ZIF@SiO 2 composite) has been synthesized through one‐step assembly process via pyrolysis etching. This employed for dehydrogenative coupling 2‐aminoalcohols with secondary alcohols, enabling efficient conversion various substrates into desired quinoline pyridine derivatives yield up to 94 %.

Cascade Performance of Nitroarenes with Alcohols Boosted by a Hollow Flying Saucer-Shaped Ni–Al₂O₃ Catalyst via a MOF-Templated Strategy Induced by the Kirkendall Effect

Inorganic Chemistry, Journal Year: 2023, Volume and Issue: 62(51), P. 21470 - 21478

Catalysts with an open hollow structure can enhance the mass transfer capability of catalyst during reaction process, thereby further improving catalytic performance. In this work, uniform and monodisperse flying-squircher-shaped Al-MOFs were synthesized via a solvothermal method. Furthermore, Al2O3-supported metallic Ni (termed Ni–Al2O3–HFA) was Kirkendall effect for hydrogenation–alkylation cascade by employing as-synthesized as carrier impregnation Ni(NO3)2·6H2O through calcination reduction. Various characterizations (e.g., XRD, HADDF-STEM, H2-TPR) conducted to reveal superior performance developed Ni–Al2O3–HFA compared Ni/Al2O3–IWI (Al2O3 obtained from Al-MOFs) in between nitroarenes alcohols. We hope use MOF template method prepare nanocatalysts, which provide guideline preparation other materials.

ABSTRACT In this study, a type of highly distinctive functional cerium‐based metal–organic frameworks (MOFs) materials was successfully prepared. The prominent feature material lies in the fact that it contains considerable number uncoordinated imine groups, and labeled as Ce‐H 2 salen. Meanwhile, by taking advantage unique complexation reaction between iron element hexamethylenetetramine, two MOFs were combined to form named Fe‐ hmta . species uniformly systematically dispersed within molecular structure This arrangement not only optimized material's microscopic but also established foundation for enhancing its subsequent performance. Subsequently, above with different functions innovatively integrated organically, finally, @Ce‐H salen composite obtained. A variety characterization techniques employed, including XPS, FT‐IR, UV–Vis, HADDF‐STEM, investigate interaction mechanisms analyze distribution on MOFs. Importantly, as‐synthesized catalyst demonstrates exceptional performance alcoholysis epoxides. indicates has potential be promising other epoxides well.
