A series of cerium-based high-entropy oxide catalysts (the ratio of CeO 2 and HEO is 1:1) was prepared by a solid-state reaction method, which exploit their unique structural and performance advantages. The Ce-HEO-T samples can achieve 100% toluene conversion rate above 328 o C when they were used as catalysts directly. …
