خلاصه مقاله:
A significant percentage of researches on fuel cells are focused on the presentation of electrocatalysts for the oxidation of alcohols [1]. Due to different properties of metal oxides such as: low thermal conductivity, great thermal stability and high resistance to chemical degradation [2]; they can be a convenient support for catalytic particles. In the present study, the solution combustion synthesis method (SCS) was utilized to fabricate NiO with high surface area and large porosity using glycine as a fuel. A self-sustained exothermic reaction among organic fuels (e.g., glycine) and oxidizers (e.g., metal nitrates) is occurred in SCS; so that, the combustion of organic fuels produced a much amount of gaseous products like H2O, CO2 H2, CO, and N2, leading to porous structures. In the following, the crystalline phases of as-prepared NiO were identified by X-ray diffractometer. Also, the morphology and particles size of the powder were detected through the scanning electron microscope. Then, the palladium nanoparticles were reduced onto the surface and into pores of NiO powder. The electro-catalytic activity of resultant nanocomposite was investigated towards the oxidation of methanol in alkaline solution by using electrochemical techniques.
