“…The nontoxicity, low price, limited permeability, and high energy content of ethanol (LF2) caused it to be considered as an appropriate option of fuel in the fuel cells. Nevertheless, the primary challenge in LF2 electrooxidation is breaking the bond of carbon–carbon for complete electrooxidation to CO 2 and making numerous intermediates 19 . The electro‐ and chemical oxidation of formaldehyde (LF3) has been considered in different fields due to: (1) serious side effects on human health in electrochemical sensors, (2) converting to harmless CO 2 and H 2 O in the mild condition in the pollutants removal process, (3) ability to reduce in the electroless metals deposition, and (4) high potential as an electron donor in the SPFCs and the production of great current density 20,21 .…”

The spongy nickel oxide (SNO) was synthesized the solution combustion method. The SNO was selected as a promoter to boost the catalytic activity of nanoraspberry‐like palladium (NRPd) toward electrooxidation of five light fuels (LFs): methanol, ethanol, formaldehyde, formic acid, and ethylene glycol. The X‐ray powder diffraction, Fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscopy, and field emission scanning electron microscope techniques were used for the materials characterization. In comparison with nonpromoted Pd, the NRPd‐SNO electrocatalyst shown an excellent efficiency in parameters like the electrochemical active surface area and anti‐CO poisoning behavior. The turnover data and the parameters, including reaction order, activation energy, and the coefficients of electron transfer and diffusion, were evaluated for the each process of LFs electrooxidation. The outcome for NRPd‐SNO activity toward LFs electrooxidation was compared to some reported electrodes. The SNO increases the removal of intermediates created in the oxidation of LFs that can poison the surface of palladium catalyst. This is due to the presence of the lattice oxygens in SNO structure and Ni switching between its high and low valances. The compatibility of the adsorption process of LFs on the surface of the NRPd‐SNO catalyst with different isotherms was determined by studying the Tafel polarization and calculating the surface coverage.
