Abstract:Intermetallic FeMnPt nanoparticles with fine sizes (4−7 nm) and ordered phases (L1 0 and L1 2 ) were successfully synthesized by a facile one-step solid-state reaction method. NaCl powder with size less than 10 μm was employed as the solid-state isolate medium and the mass ratio of precursors to NaCl powders was set as 1:300; the solid reaction was done at 780 °C under a reducing atmosphere (90% Ar + 10% H 2 ) for 180 min. The electrocatalytic hydrogen evolution reaction (HER) performances in both acidic and a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
