In this work, we introduce a novel ZnTe/quinhydrone (ZnTe/QH) nanocomposite as an excellent catalyst for electro-oxidation of ethanol in alkaline medium. The ZnTe semiconductor nanorods were synthesized by a novel chemical route. The synthesized product was characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), FT-IR spectroscopy, and cyclic voltammetry techniques. Then, this product along with quinhydrone were used for the electrocatalytic oxidation of ethanol in alkaline medium. The ZnTe/QH/GCE showed a higher electrocatalytic activity toward ethanol oxidation. The performance of catalyst was evaluated by electrochemical measurements such as cyclic voltammetry and electrochemical impedance spectroscopy using the three-electrode system. Furthermore, the ZnTe/QH/GCE displayed a higher stability with 93% retention of the initial current density after 6000 s in long term current-time curve. This newly prepared ZnTe/QH nanohybrid could be a promising anodic catalyst for the direct ethanol fuel cells (DEFCs) application.
