In view of a possible use as anode materials in acidic direct alcohol fuel cells, the electro-catalytic activity of Pt-Ni and Pt-M-Ni (M = Ru, Sn) catalysts for methanol and ethanol oxidation has been widely investigated. An overview of literature data regarding the effect of the addition of Ni to Pt and Pt-M on the methanol and ethanol oxidation activity in acid environment of the resulting bi...

The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by physical adsorption of bilirubin oxidases from Myrothecium verrucaria. The existence of an alternative resting form of the enzyme is validated. ...

Cellulose is expected to have a key role in the sustainable society in the future. This natural polysaccharide can be used as alternative raw material to petrochemical products. Cellulose based functional materials can be modified to desired applications by changing their physicochemical properties. Chemical and/or biochemical reactions have so far been used to modify chemical groups on cellulo...

In the present study, Nickel-Copper nanoparticles were electrodeposited on glassy carbon electrode (GCE) by using electroplating deposition method. The prepared electrode was characterized by scanning electron microscopy (SEM) and elemental mapping analysis. Results showed that Ni-Cu nanoparticles with a high density are distributed at the surface of the glassy carbon electrode. Subsequentl...

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 activ...

The integration of electro and bio-catalysis offers new ways making molecules under very mild, environmentally benign conditions. We show that TEMPO mediated electro-catalytic oxidation alcohols can be adapted to work in aqueous buffers, with minimal organic co-solvent, enabling biocatalytic reductive amination using the AdRedAm enzyme. combined process a approach amine alkylation native alcoho...

Catalytic combustion is a promising technique for producing thermal energy in MEMS(Micro Electro-Mechanical Systems) scale electrical power generators. To examine the feasibility and possible benefits of catalytic combustion in MEMS-scale channels, catalytic reactions in small diameter (1 mm) flow reactor tubes at low Reynolds numbers are simulated by using the commercial fluid dynamics code FL...
