Controlled growth cerium oxide nanoparticles on reduced graphene oxide for oxygen catalytic reduction
Electrochimica Acta（2016）
Abstract
•Rare earth metal oxide/graphene electrocatalyst with ORR activity was reported.•Electrocatalyst was synthesized by thermal treatment of Ce3+-doped GO.•Crystallization of CeO2 can be controlled through thermal treatment temperature.•CeO2/rGO nanocomposites obtained at 750°C exhibits superior ORR activity.•Synergistic effect of CeO2 and rGO makes catalyst high performance.
