Data from Xiamen University Provide New Insights into Nanocrystals

June 27, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Researchers detail new data in Nanocrystals. According to news originating from Xiamen, People's Republic of China, by VerticalNews correspondents, research stated, "Noble metal nanocrystals (NCs) enclosed with high-index facets hold a high catalytic activity thanks to the high density of low-coordinated step atoms that they exposed on their surface."

Our news journalists obtained a quote from the research from Xiamen University, "Shape-control synthesis of the metal NCs with high-index facets presents a big challenge owing to the high surface energy of the NCs, and the shape control for metal Rh is even more difficult because of its extraordinarily high surface energy in comparison with Pt, Pd, and Au. The successful synthesis is presented of tetrahexahedral Rh NCs (THH Rh NCs) enclosed by {830} high-index facets through the dynamic oxygen adsorption/desorption mediated by square-wave potential."

According to the news editors, the research concluded: "The results demonstrate that the THH Rh NCs exhibit greatly enhanced catalytic activity over commercial Rh black catalyst for the electrooxidation of ethanol and CO."
