▎ 摘　　要

A new method for obtaining platinum, palladium, and rhodium nanoparticles on graphene (G) flakes via the reduction of an intermediate nanocomposite on the surface of graphene oxide (GO) in supercritical 2-isopropanol is described. The thus-prepared nanocomposites based on graphene and graphene oxide were characterized using transmission electron microscopy (TEM), including high-resolution microscopy; X-ray powder diffraction; and X-ray photoelectron spectroscopy (XPS).
