摘要: Abstract Nanocomposite coatings of Ni–Cr 2 O 3 supported on carbon electrodes have been prepared by electrodeposition technique from nickel Watts bath in presence Cr nanoparticles. Their electrochemical catalytic activities evaluated towards electrooxidation ethanol 1.0 M NaOH solution using cyclic voltammetry, chronoamperometry and Tafel plots. The performance the anodes as a function co-deposited content was studied. activity fabricated increases with increasing volume fraction percent (V f %) deposited film up to 7V %. /C (7V electrode displayed significantly enhanced stability compared Ni/C electrode. kinetic parameters Ni(OH) /NiOOH oxidation at evaluated.
