In this study, a novel preparation of mesoporous NiCo2O4-MWCNT nanocomposite aerogels based on sol gel technique is proposed. Multiwall carbon nanotube (MWCNT)-supported NiCo2O4 nanocomposite aerogels as an efficient catalyst for the ethanol electro-oxidation is reported. The MWCNTs exhibit an interconnected fibrous network with uniform dispersion of NiCo2O4 nanoparticles. The effects of MWCNT concentration on the ethanol electro-oxidation of MWCNT/NiCo2O4 aerogels are studied. We found that using a proper loading of MWCNTs allowed us to reach higher current densities for the oxidation of ethanol in an alkaline media. The highly porous and fibrous MWCNT/NiCo2O4 aerogels are the promising electro-catalysts for the oxidation of a direct ethanol fuel cell. (C) 2016 Hydrogen Energy Publications LLC.
