Abstract
CoCr7C3-like nanorods encapsulated in carbon nanofibers shell [CoCr7C3-CNFs] were prepared using a simple electrospinning technique. The as-prepared nanocomposite was physically characterized using XRD, SEM, TEM and EDX analysis techniques. The electrocatalytic activity of CoCr7C3-CNFs was examined for methanol electro-oxidation in alkaline medium using cyclic voltammetry and chronoamperometry. The fabricated CoCr7C3-CNFs revealed good electroactivity towards methanol oxidation reaction. The measured low onset potential value [â80Â mV (Ag/AgCl)] implied a marked enhancement in the oxidation kinetics at CoCr7C3-CNFs surface. Chronoamperometry test also displayed an increased steady state oxidation current density value of 18.42Â mAÂ cmâ2 at 400Â mV after 1800Â s. This synthesized low cost, highly active and stable nanocomposite could be widely employed as a promising anode material in direct methanol fuel cells.
