Abstract

In this study, the electrochemical oxidation of glycerol was investigated using a nickel-based metal-organic framework (Ni-MOF)/multiwall carbon nanotube (CNT) composite electrode. The surface morphology of the composite electrode was characterized by scanning electron microscopy (SEM). Cyclic voltammetry was employed to assess the electrocatalytic performance for glycerol oxidation, while chronoamperometry was used to evaluate electrode stability via current-time curves. The electrochemical performance of the Ni-MOF was compared before and after compositing with CNTs. The results demonstrate that the Ni-MOF/CNT composite electrode exhibits enhanced electrocatalytic activity for glycerol oxidation, attributed to the synergistic effects of the CNTs’ high electrical conductivity and large surface area and the Ni-MOF’s high electrocatalytic activity and porous structure. These properties make the composite a promising material for glycerol fuel cell applications.
