Preparation and Characterization of Carbon Nanotubes- Supported Pt-SiW12O40 Catalyst for Electrooxidation of Cyclohexane to Cyclohexanone/Cyclohexanol

International Journal of Electrochemical Science, 2014
H4SiW12O40 (abbreviated as SiW) and Pt supported on carbon nanotubes (CNTs) with different Pt/SiW ratios were prepared and characterized by FTIR, XRD, ICP-OES, polarography, and TEM. The prepared catalysts were then after attached onto glassy carbon (GC)

Using Cyclohexanol as a Co-Surfactant in the Synthesis of New Mesoporous Silica Particles [PDF]

علوم و تکنولوژی پلیمر, 2014
In the synthesis of mesoporous silica particles, the geometry, pore size, and specific surface area and pore volume of the particles can be greatly influenced by selected media and method, selection of co-solvent and co-surfactant. In this study, new SPB

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Production of Adipic Acid from Mixtures of Cyclohexanol-Cyclohexanone using Polyoxometalate Catalysts

Makara Journal of Science, 2015
Adipic acid production through catalytic conversion of cyclohexanol-cyclohexanone using polyoxometalate H5[a-BW12O40] and H4[a-SiW12O40] as catalysts was carried out systematically. Polyoxometalates H5[a-BW12O40] and H4[a-SiW12O40] were synthesized using

Redox Biocatalysis in Lidocaine‐Based Hydrophobic Deep Eutectic Solvents: Non‐Conventional Media Outperform Aqueous Conditions

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Two hydrophobic DESs, lidocaine/oleic acid and lidocaine/decanoic acid, were utilized as reaction media that were enzyme‐compatible and highly substrate‐solubilizer for carbonyl reduction catalyzed by horse liver alcohol dehydrogenase, focusing on the effect of water contents and on maximizing substrate loadings, which showcases for the first time the ...

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...

Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.
