By a News Reporter-Staff News Editor at Energy Weekly News -- Investigators publish new report on Alcohols. According to news reporting originating from Trondheim, Norway, by VerticalNews correspondents, research stated, "The present work presents a method to encapsulate pre-synthesised Ru nanoparticles (NPs) by Pt using a polyol method without capping agents at various pH values (6, 7, 8 and 10). The structural and surface properties of the catalysts were characterised using X-ray diffraction, transmission electron microscopy, CO stripping, and energy-dispersive X-ray spectroscopy."
Our news editors obtained a quote from the research from the Norwegian University of Science and Technology (NTNU), "The studies suggest that the pH during encapsulation of Ru by Pt plays an important role in controlling of shell composition. A core shell catalyst with an alloy shell was obtained at a pH of 6, whereas a monometallic Pt shell was obtained at a pH of 10. The core shell catalysts gave higher steady-state current for methanol oxidation: 10-fold higher for alloy shells and 5-fold higher for Pt-enriched shells compared to the pure Pt catalyst."
According to the news editors, the research concluded: "It is suggested that the highest catalytic enhancement of the core shell catalysts is obtained through the bi-functional character that dominates the alloy shells rather than the ligand-effect-promoted Pt-enriched shells."
