Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Dual‐Stabilized Single‐Site Fe(II) for Catalytic Conversion of CO2 to Propiolic Acid Under Ambient Condition

open access: yesEcoEnergy, EarlyView.
We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.

Recent Developments in Azomethine Ylide-Initiated Double Cycloadditions

open access: yesMolecules
Azomethine ylides (AMYs) have a nitrogen–carbon double bond and an electron lone pair on the nitrogen atom. They are essential 1,3-dipoles for [3+2] cycloadditions in the synthesis of pyrrolidine-containing heterocycles.

Optimally Carbonized Mangrove Wood–Derived Hard Carbon with a Soft Carbon Coating for High‐Performance Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...
