The Kinetics for the Electrochemical Synthesis of Adipic Acid

open access: yesInternational Journal of Electrochemical Science, 2011
A new method of synthesis of adipic acid from cyclohexanol was reported. The electrochemical oxidation process was investigated by polarization curve by taking Ti/SnO2+Sb2O3/PbO2 as anode and Cr2O72-/Cr3+ as indirect oxidant.

Cytotoxic, Genotoxic, and Mutagenic Effects of Organotellurane RF07 in Female Swiss Mice (Mus musculus)

open access: yesChemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT The organotellurane RF07 (RF07) is an organic compound containing tellurium, a rare semi‐metal, and its leishmanicidal and antimalarial activity has already been reported in previous studies. This study evaluated the toxic effects of RF07 at 0.42, 21.37, and 42.75 mg/kg using comet assay, micronucleus test, and hematological/biochemical tests ...

The Role of Hydrogen Spillover on Ru/MoO3 in the Hydrodeoxygenation of Phenol as a Lignin Model Compound

open access: yesChemCatChem, Volume 18, Issue 5, 13 March 2026.
MoO3 is active for hydrodeoxygenation of phenol at high temperatures. Ru/MoO3 gives high conversions and selectivities at lower temperature. Catalytic performance correlates with both Ru content and the concentration of Mo–OH sites on the surface (formed by hydrogen spillover from Ru) but not with the amount of reduced Mo centers (oxygen vacancies). Mo–

Electronic Modulation of CoNi Nanoparticles by N‐Doped Carbon for Efficient Lignin Hydrogenolysis to Aromatic Monomers

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...
