ABSTRACT
Direct liquid fuel cells (DLFCs) have received significant attention as a promising
alternative renewable energy source.1 The limited and environment harmful effect of the
petroleum-based energy sources are the major intensives to use DLFCs in the last decades
attributing to their unique features over the traditional hydrogen fuel cells, including high
.
energy density, easy handling, transport, and storage 2–4. Herein, glycerol
electrooxidation is studied in alkaline medium on Nickel oxide nanoparticles modified
carbon felt (CF) anodes. X-ray diffraction (XRD) and cyclic voltammetry (CV) were used
to address the change in the electrodeposited Nickel oxide phase. Contact angle, X-ray
photoelectron spectroscopy (XPS) and Raman spectroscopy were used to investigate the
changes in CF after treatment. Interestingly, pre-treatment of CF enhances the catalytic
activity of Nickel oxide towards glycerol electrooxidation possibly due to the enhanced
distribution of metal oxide nanoparticles throughout the CF providing high electroactive
surface area.
