| چکیده | ||
| In this study cobalt oxide nanoparticles were electrodeposited on the surface of graphenized pencil lead electrode (GPLE) as a low cost and efficient electrocatalyst for the OER in alkaline media. The prepared cobalt oxide modified GPLE (CoOx/GPLE) was carefully characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, electrochemical impedance spectroscopy and cyclic voltammetry techniques. The developed electrocatalyst represents remarkably low OER overpotential of 1.41V (vs. RHE) at the current density of 10 mA cm-2 and Tafel slope of 149 mV dec-1 in 0.1 M KOH solution. The CoOx/GPLE was highly stable and capable for maintaining catalytic activity for at least 5 h. Due to distinctive electrical conductivity, high mass transfer, and adequate active sites of GPLE, the electrocatalytic activity of the cobalt oxide nanoparticles were incredibly improved in CoOx/GPLE. | ||
