Core–shell structured CeO2@MoS2 nanocomposites for high performance symmetric supercapacitors

Abstract

MoS2 ultrathin nanosheet-coated CeO2 hollow sphere (CeO2@MoS2) nanocomposites with a 3D core–shell architecture were successfully prepared via a facile wet chemistry strategy. The core–shell structured CeO2@MoS2 nanocomposites were systematically characterized using XRD, SEM, TEM and XPS analysis techniques. As a proof of concept application, symmetric supercapacitors were assembled using the CeO2@MoS2 nanocomposites, and aqueous 1 M Na2SO4 or 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid as the electrolyte. The as-obtained CeO2@MoS2 nanocomposites exhibited superior performance in symmetric supercapacitors.
