Oxygen Reduction at Soft Interfaces Catalyzed by In Situ-Generated Reduced Graphene Oxide

Hubert Girault, Fernando Cortes Salazar, Micheal Diarmaid Scanlon, Véronique Amstutz, Haiqiang Deng

Face to face: Flakes of reduced graphene oxide, synthesized in situ at the liquid/liquid interface from a graphene-oxide precursor, are capable of catalyzing the biphasic reduction of protons to hydrogen peroxide in the presence of molecular oxygen and an ...

A novel platinum nanocatalyst for the oxidation of 5-Hydroxymethylfurfural into 2,5-Furandicarboxylic acid under mild conditions

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Duncan Thomas Lindsay Alexander, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key intermediate obtainable from various cellulosic (biomass) derivatives, but it must be converted to other chemicals such as 2,5-Furandicarboxylic acid (FDCA) for direct use. FDCA is an important derivative of HMF as it ...

Synthesis of Electron-Rich Uranium(IV) Complexes Supported by Tridentate Schiff Base Ligands and Their Multi-Electron Redox Chemistry

Marinella Mazzanti, Julie Renée Michelle Andrez

The synthesis, structure, and reactivity of a new complex of U(IV) with the tridentate Schiff base ligand Menaphtquinolen are reported. The reduction of the bis-ligand complexes [UX2(Menaphtquinolen) 2] (X = Cl, (1-Cl); I (1-I)) with potassium metal afford ...

Magnetic communication and reactivity of a stable homometallic cation-cation trimer of pentavalent uranyl

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reaction of the UO2+ precursor [(UO 2Py5)(KI2Py2)]n, with the potassium salt of the tetradentate aza β-diketiminate ligand L (L = 2-(4-tolyl)-1,3-bis(quinolyl)malondiiminate) affords the ...

Biomimetic Oxygen Reduction by Cofacial Porphyrins at a Liquid-Liquid Interface

Hubert Girault, Pekka Eero Peljo

Oxygen reduction catalyzed by cofacial metalloporphyrins at the 1,2-dichlorobenzene-water interface was studied with two lipophilic electron donors of similar driving force, 1,1'-dimethylferrocene (DMFc) and tetrathiafulvalene (TTF). The reaction produces ...

Oxygen and hydrogen peroxide reduction by 1,2-diferrocenylethane at a liquid/liquid interface

Hubert Girault, Pekka Eero Peljo, Fernando Cortes Salazar, Peiyu Ge, Haiqiang Deng

Molecular oxygen and hydrogen peroxide reduction by 1,2-diferrocenylethane (DFcE) was investigated at a polarized water/1,2-dichloroethane (W/DCE) interface. The overall reaction points to a proton-coupled electron transfer (PCET) mechanism, where the firs ...

Fine tuning of the catalytic effect of a metal-free porphyrin on the homogeneous oxygen reduction

Hubert Girault, Zdenek Samec

The catalytic effect of tetraphenylporphyrin on the oxygen reduction with ferrocene in 1,2-dichloroethane can be finely tuned by varying the molar ratio of the acid to the catalyst present in the solution. The mechanism involves binding of molecular oxygen ...

Passerini Three-Component Reaction of Alcohols under Catalytic Aerobic Oxidative Conditions

Jieping Zhu

Alcs. instead of aldehydes were used in the Passerini three-component reaction under catalytic aerobic conditions. Mixing alcs., isocyanides, and carboxylic acids in toluene in the presence of a catalytic amt. of cupric chloride, NaNO2, and TEMPO afforded, ...

Nitrous Oxide Abatement over Fe-Zeolite

Bryan Bromley

The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...
