Nanostructured (100-x)% Pd -x % Ni (x = 1, 2, 5, 10, and 20) and (90 – y)%Pd-10%Ni-y%C (y = 0.5, 1, 2, 5, and 10) composite films are obtained on glassy carbon electrodes and characterized by XRD, TEM, cyclic voltammetry and chronoamperometric techniques for use as electrocatalysts towards methanol, ethanol, ethylene glycol and glycerol oxidations in 1 M KOH at 25°C. Results show that addition ...

Porous Pt nanowire arrays show enhanced electrocatalytic activities for ethanol oxidation in direct alcohol fuel cells.

The use of single crystal electrodes in electrocatalysis have allowed researchers to understand some of the elementary steps in different reactions and to establish some relationships between the activity of an electrocatalyst and its surface structure. But the precise identification of the particular type of crystallographic site on a nanoparticle sized electrocatalyst where the reaction takes...

A novel and sensitive electrode was suggested for the rapid determination of ascorbic acid (AA) using a glassy carbon (GCE) modified with synthesized MAPbI3 L-cys (L-cys/MAPbI3/GCE). Determination as an important component human diet due to help in decreasing blood pressure improving endothelial function is crucial. The characterized by different methods, including transmission electron microsc...

— Salen type chromium Schiff base complex was synthesized by microwave irradiation. The complex was characterized by UV-visible, FT-IR spectroscopy and EPR spectroscopy. Electrochemical property of chromium complex was tested with the aid of cyclic voltammetry (CV). The synthesized chromium Schiff base complex was electrochemically polymerized and used for the detection of hydroquinone. Chromiu...

A graphene nanosheets (GNS) film coated glassy carbon electrode (GCE) was fabricated for sensitive determination of tyrosine (Tyr). The GNS-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. The voltammetric techniques were employed to study electro-oxidation of Tyr. The results revealed that the modified electrode showed an electrocatalyt...

Nickel microspheres were synthesized via a water-in-oil reverse nanoemulsion system using nickel nitrate as the nickel precursor and hydrazine hydrate as the reducing agent. The nanoemulsion was a triton X-100/cyclohexane/water ternary system. The surface morphology of the nickel microspheres was studied by scanning electron microscopy, which indicated that the microspheres had a nanoporous str...
