We report cuboctahedral Pd nanoparticles on WC synthesized by the polyol process using ethylene glycol with NO(3)(-) and Fe(3+)/Fe(2+) ions. The cuboctahedral Pd/WC shows much improved electrocatalytic activity for methanol electrooxidation in alkaline solution.

Highly graphitic carbon nanocoils (GCNC) were synthesized through the catalytic graphitization of carbon microspheres obtained by the hydrothermal carbonization of different saccharides (sucrose, glucose and starch) and were used as a support for Pt nanoparticles. The Pt nanoparticles were deposited by means of a polymer mediatedpolyol method. The Pt catalysts were characterized both physically...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...

The slow, incomplete oxidation of methanol and ethanol on platinum-based anodes as well as the high price and limited reserves of Pt has hampered the practical application of direct alcohol fuel cells. We describe the electrocatalysts consisting of one Pt monolayer (one atom thick layer) placed on extended or nanoparticle surfaces having the activity and selectivity for the oxidation of alcohol...

The incorporation of P into Pt–Co nanoalloys is used to regulate the electron density around Pt for high-efficiency methanol electrooxidation.

Electrooxidation of methanol was realised on platinum and perchlorate anion doped polypyrrole film electrodes in acidic media. A systematic kinetic investigation was performed and optimum experimental conditions for the preparation of the electrocatalytic system were determined. The presence of ClO4 − anions was confirmed by XPS analysis of the doped polymer matrix. © 2001 Elsevier Science B.V....

An efficient synthetic approach that enables not only the control of Pt nanocubes but also the one-pot fabrication of novel Pt nanocube assemblies was developed for the first time. The integration of well-defined building blocks and unique superstructures endows Pt nanocube assemblies with enhanced performance in the methanol electrooxidation, showing a new concept for further enhancing the per...

Ultrafine Pt nanoparticles supported on a robust 3D N-doped porous graphene (PtNP/R-3DNG) composite are fabricated. The composite exhibits a considerable enhancement of activity and stability toward the methanol electrooxidation reaction. The robust 3D porous structure and abundant nitrogen atoms are believed to be responsible for the enhanced performance.

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 ...
