The Electrocatalysis of Ethanol Oxidation
In this paper, the main characteristics of ethanol electrooxidation are presented and the results of electrochemical and spectroscopic methods are discussed. The total oxidation reaction should produce 12 e/molecule. However, on Pt catalysts, the reaction follows parallel pathways forming acetaldehyde, acetic acid and carbon dioxide as soluble products. Thus much lower yields of charge per etha...
متن کاملNickel-cobalt bimetallic anode catalysts for direct urea fuel cell
Nickel is an ideal non-noble metal anode catalyst for direct urea fuel cell (DUFC) due to its high activity. However, there exists a large overpotential toward urea electrooxidation. Herein, NiCo/C bimetallic nanoparticles were prepared with various Co contents (0, 10, 20, 30 and 40 wt%) to improve the activity. The best Co ratio was 10% in the aspect of cell performance, with a maximum power d...
متن کاملCO2 emission free co-generation of energy and ethylene in hydrocarbon SOFC reactors with a dehydrogenation anode.
A dehydrogenation anode is reported for hydrocarbon proton conducting solid oxide fuel cells (SOFCs). A Cu-Cr(2)O(3) nanocomposite is obtained from CuCrO(2) nanoparticles as an inexpensive, efficient, carbon deposition and sintering tolerant anode catalyst. A SOFC reactor is fabricated using a Cu-Cr(2)O(3) composite as a dehydrogenation anode and a doped barium cerate as a proton conducting ele...
متن کاملDevelopment of plasma sprayed molybdenum carbide-based anode layers with various metal oxides for SOFC
Air plasma sprayed (APS) coatings provide an ability to deposit a range of novel fuel cell materials at competitive costs. This work develops three separate types of composite anodes (Mo-Mo2C/Al2O3, Mo-Mo2C/ZrO2, Mo-Mo2C/TiO2) using a combination of APS process parameters on Hastelloy ® X for application in intermediate temperature proton conducting solid oxide fuel cells. Commercially availabl...
متن کاملStructural and defect chemistry guidelines for Sr(V,Nb)O3-based SOFC anode materials.
Structural and defect chemistry guidelines were used for Nb-substituted SrVO3-δ materials, designed to meet SOFC anode requirements, with emphasis on redox tolerance, thermochemical compatibility with other SOFC materials, electrical conductivity and adjustable changes in oxygen stoichiometry for their prospective impact on electrocatalytic performance. SrV1-xNbxO3-δ (x = 0-0.30) ceramics were ...
