This investigation is used to verify the possibility of using the Ni-MOF/CNTs electrode in the ethylene glycol fuel cells. The morphology of the composite layer on the surface of the electrode substrate was examined by scanning electron microscopy (SEM). The cyclic voltammetry technique was used to examine the typical electrocatalytic performance of the electrode. In 0.1 M NaOH solution, well-defined oxidation and reduction peaks of Ni²⁺/Ni³⁺ redox couple were observed. The electrocatalytic current at the Ni-MOF electrode was also studied for comparison with that of the Ni-MOF/CNTs electrode. Owing to the synergetic effect of the MOF and the CNTs, the Ni-MOF/CNTs electrode shows a satisfactory electrocatalytic activity toward the EG electro-oxidation, making it a promising candidate for use as an ideal anode material in direct alkaline alcohol fuel cells. https://www.abechem.com/article_714691_a5c5d8b30555700f3dfe38bc6d76b6a4.pdf
