چکیده
|
The electrocatalytic oxidation of ethanol was studied for the platinum nanoparticles/ functionalized carbon nanoparticles composites supported at the carbon-ceramic electrode (ptnps/tosyl-cnps/cce) as an electrocatalyst in acidic medium. the ptnps/tosyl-cnps/cce electrocatalyst was synthesized by electrodeposition of ptnps on/in casted tosyl-cnps at the cce. the characterization of the fabricated nanocomposite was done by x-ray powder diffraction (xrd) spectroscopy, field emission scanning electron microscopy (fe-sem) and energy-dispersive x-ray (edx) spectroscopy. the obtained electrocatalytic oxidation of ethanol was studied by cyclic voltammetry and chronoamperometry techniques. the results showed that the ptnps/tosyl-cnps/cce was electrocatalytically more active than ptnps/cce and had high anodic peak current densities, low onset potential, low poisoning and high stability. hence, the proposed nanocomposite, ptnps/tosyl-cnps/cce, can be extended as an attractive and promising electrocatalyst for the ethanol electrooxidation reaction in fuel cells.
