New Nanosheets Study Results Reported from Xiamen University

May 9, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Nanosheets have been published. According to news reporting originating from Xiamen, People's Republic of China, by VerticalNews correspondents, research stated, "Ultrathin crystalline nanosheets give an extremely high surface area of a specific crystal facet with unique physical and chemical properties compared with normal three-dimensionally polyhedral nanocrystals (NCs). However, the ultrathin metal nanosheets tend to curl themselves or assemble with each other sheet by sheet, which may reduce the effective surface area and accordingly the catalytic activity to a great extent."

Our news editors obtained a quote from the research from Xiamen University, "Here we report a facile wet-chemical route that allows the fabrication of novel excavated rhombic dodecahedral (ERD) PtCu3 alloy NCs with ultrathin nanosheets of high-energy {110} facets. The surface area was measured to be 77 m(2) g(-1) by CO stripping, although the particle size is about 50 nm."

According to the news editors, the research concluded: "Electrochemical characterizations showed that the ERD PtCu3 NCs exhibit excellent electrocatalytic performance and high antipoisoning activity in comparison with commercial Pt black and PtCu3 alloy NCs with {111} surfaces."
