The nanoparticles were characterized by infrared spectroscopy (IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). Then, the effect of Nd-Co3O4 on the electrocatalytic activity of gold nanodendrites (AuNDs) electrodeposited on a glassy carbon electrode (GCE) for ethanol oxidation was studied. The results showed that the Nd-Co3O4/AuNDs/GCE presents higher active surface area and current density (about 2 times) for the ethanol oxidation compared with the AuNDs/GCE.  Cyclic voltammetry and chrono-potentiometry methods proved that the Nd-Co3O4/AuNDs/GCE is able to increase a long-term stability of electrode in alkaline ethanol fuel cell by providing OHads species at the surface of the catalysts. Consequently, the Nd-Co3O4/AuNDs/GCE, as an anodic electrode, reveals potent catalytic activity for ethanol oxidation in alkaline media. %U https://icc.journals.pnu.ac.ir/article_9788_5102ab3984e3dd415bee96b68d7ac3e9.pdf
