Aerogels, 3D network-structured porous materials, have been widely studied for catalysts themselves or catalyst supports, owing to their high specific surface areas and porosities. However, when supported metal is used for catalysis, especially single atoms, metal–support-interactions (MSIs) play a vital role for catalysis. Aerogels have huge potential in the perspective of MSIs. Many previous studies have reported that morphologies of supports significantly affected MSIs between support and loaded metal, and aerogels have unique morphologies that can be tuned via simple control. In this work, we fabricated cerium oxide-based aerogels as support and loaded copper oxide. Oxidation states of supported copper was significantly affected by structure variation of cerium oxide-based aerogels, and it affected CO oxidation acitivity.
