Hydrothermal and Solvothermal Synthesis of Cerium-Zirconium Oxides for Catalyst Applications
International Journal of Technology, 2019 Cerium oxide (CeO2) is a rare earth metal oxide that has high oxygen storage capacity at low temperature. In order to enhance this capacity, as well as its thermal stability, it is necessary to combine CeO2 with zirconium oxide (ZrO2).
