Morphological Effect of Pd Catalyst on Ethanol Electro-Oxidation Reaction
In the present study, three different structures with preferentially exposed crystal faces were supported on commercial carbon black by the polyol method (nanoparticles (NP/C), nanobars (NB/C) and nanorods (NR/C)). The electrocatalysts were characterized by XRD, TEM, TGA and cyclic voltammetry at three different ethanol concentrations. Considerable differences were found in terms of catalytic e...
متن کاملRecent Advances on Electro-Oxidation of Ethanol on Pt- and Pd-Based Catalysts: From Reaction Mechanisms to Catalytic Materials
The ethanol oxidation reaction (EOR) has drawn increasing interest in electrocatalysis and fuel cells by considering that ethanol as a biomass fuel has advantages of low toxicity, renewability, and a high theoretical energy density compared to methanol. Since EOR is a complex multiple-electron process involving various intermediates and products, the mechanistic investigation as well as the rat...
متن کاملKinetic study of ethanol and methanol electro-oxidation on Pd-vulcan XC-72R/Cu electrocatalyst in alkaline media
Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...
متن کاملEthanol electro-oxidation on Pt/C and Pd/C catalysts in alkaline media
Recently, increasingly attentions have been paid to the electro-oxidation of ethanol in alkaline media in the context of using ethanol as a fuel in anion-exchange membrane fuel cell. Alkaline media presents several advantages compared to acidic media. It has been found that the electrocatalytic activity for etanol oxidation in alkaline media is much higher than that in acidic media [1]. Further...
متن کاملOne-Pot Synthesis of Graphene-Supported Monodisperse Pd Nanoparticles as Catalyst for Formic Acid Electro-oxidation
To synthesize monodisperse palladium nanoparticles dispersed on reduced graphene oxide (RGO) sheets, we have developed an easy and scalable solvothermal reduction method from an organic solution system. The RGO-supported palladium nanoparticles with a diameter of 3.8 nm are synthesized in N-methyl-2-pyrrolidone (NMP) and in the presence of oleylamine and trioctylphosphine, which facilitates sim...
