Co/CeO₂/C composites derived from bimetallic metal–organic frameworks for efficient microwave absorption

Abstract

CeO2, as an n-type semiconductor material, has been widely used in microwave absorption (MA), which can be due to its unique structural features such as oxygen vacancies and interstitial atoms....

“…An n-type semiconductor substance called cerium dioxide (CeO 2 ) has several uses in electrocatalysis, , solar cells, and photocatalysis . When considering the availability of resources, CeO 2 is more affordable and plentiful in the earth’s crust than lanthanide oxides such as La 2 O 3 , Gd 2 O 3 , and Y 2 O 3 . Furthermore, concerning its structural properties, CeO 2 can react more quickly to EMW than other metal oxide-based MA materials like Fe 2 O 3 and ZnO, which in turn causes polarization effects.…”

Additionally, because Ce atoms can readily switch between their oxidation states, Ce 4+ and Ce 3+ , they can adapt well to their surroundings.…”
