Abstract
|
In this study, Fe3O4@Pt core-shell nanoparticles are synthesized by a fast and simple synthesis method. X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy are used to investigate the surface morphology and chemical structural. Electrocatalytic activities of the core-shell nanoparticles have been investigated towards formaldehyde electrooxidation by cyclic voltammetry in 0.5 M H2SO4 solution. The results indicate that the Fe3O4@Pt core-shell nanoparticles showed a better electrocatalytic performance towards the formaldehyde electrooxidation compared with the Pt-alone nanoparticles.
