Reports from University of California Advance Knowledge in Chalcogens (Palladium and Gold Nanotubes as Oxygen Reduction Reaction and Alcohol Oxidation Reaction Catalysts in Base)

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Chalcogens. According to news reporting out of Riverside, California, by NewsRx editors, research stated, "Palladium (PdNTs) and gold nanotubes (AuNTs) were synthesized by the galvanic displacement of silver nanowires. PdNTs and AuNTs have wall thicknesses of 6nm, outer diameters of 60nm, and lengths of 5-10 and 5-20m, respectively."

Our news journalists obtained a quote from the research from the University of California, "Rotating disk electrode experiments showed that the PdNTs and AuNTs have higher area normalized activities for the oxygen reduction reaction (ORR) than conventional nanoparticle catalysts. The PdNTs produced an ORR area activity that was 3.4, 2.2, and 3.7times greater than that on carbon-supported palladium nanoparticles (Pd/C), bulk polycrystalline palladium, and carbon-supported platinum nanoparticles (Pt/C), respectively. The AuNTs produced an ORR area activity that was 2.3, 9.0, and 2.0times greater than that on carbon-supported gold nanoparticles (Au/C), bulk polycrystalline gold, and Pt/C, respectively. The PdNTs also had lower onset potentials than Pd/C and Pt/C for the oxidation of methanol (0.236V), ethanol (0.215V), and ethylene glycol (0.251V)."

According to the news editors, the research concluded: "In comparison to Pt/C, the PdNTs and AuNTs further demonstrated improved alcohol tolerance during the ORR."
