▎ 摘　　要

This paper describes a sequential, two-step process for the synthesis of a composite based on graphene and CeO2 nanoparticles using supercritical fluid. The process includes the reduction of a prepre-pared graphene oxide/CeO2 nanocomposite with supercritical propanol-2. The nanocomposites thus obtained have been characterized by transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.
