Diaphorase catalyzes efficiently the oxidation of NADH to NAD+ by benzylviologen. This reaction was used to regenerate the NADf required for the biocatalyzed oxidation of methanol to CO, using NADf-dependent dehydrogenases. A rnethanol/dioxygen biofuel cell was assembled using these bioreactions in the anode compartment. The open-circuit voltage of the cell was 0.8 V, and the maximum power outp...

WO 3 and /PAni, as a ceramic-polymer composite, were synthesized, characterized, evaluated electrocatalyst support for platinum toward the methanol oxidation reaction in an acid medium. Pt supported by chemical reduction (25.5 % wt) on physically mixed with chemically synthesized PAni (Pt/WO /PAni(20%)) was compared physical mixture of three materials /PAni-PM). The profiles acidic medium show ...

in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...

Using first principles quantum mechanics [nonlocal density functional theory (B3LYP)], we calculated the 13 most likely intermediate species for methanol oxidation on clusters of all 2nd and 3rd row Group VIII transition metals for all three likely binding sites (top, bridge, and cap). This comprehensive set of binding energies and structures allows a detailed analysis of possible reaction mech...

The effect of pretreatment conditions on the oxidation state and activity of micelle-synthesized Pt nanoparticles supported on ZrO2 was studied for methanol decomposition and oxidation reactions. An O2-pretreatment is observed to be effective for producing clean, stable, and active nanoparticles. Pt-oxide species formed during such pretreatments were found to have little influence in methanol d...

Iron (III) phthalocyanine complexes were employed for the first time as a mild and efficient Lewis acid catalyst in the selective oxidation of cyclohexene to cyclohexane-1,2-diol. It was found that the catalyst FePcOTf shown excellent conversion and moderate selectivity relative to other iron (III) phthalocyanine complexes. The optimum conditions of the oxidation reaction catalyzed by FePcOTf/H...
