“…19 Besides the nature and amount of defects, the catalytic activity of CeO 2 is influenced by various structural factors, such as composition, surface area, and crystal face exposure. 20 To optimize the structural properties and catalytic performance of CeO 2 , various morphologies, such as nanorods, nanotubes, nanocubes, and nanospheres, have been designed and prepared. In addition, doping or loading other metal oxides into the CeO 2 lattice can cause lattice distortion, generate redox pairs, increase the defects/vacancies concentration of CeO 2 , and provide effective strategies for improving the redox cycling ability, thermal stability, and catalytic performance of cerium-based oxide catalysts.…”
