Hydrothermal Synthesis: Low−Temperature Subcritical Water for Ceria−Zirconia Mixed Oxides Preparation

A low-temperature hydrothermal synthesis technique was employed as a medium to produce ceria−zirconia mixed oxides particles at temperatures of 200–300 °C and pressure of 10 MPa in a batch process. At these conditions, the average crystallite sizes of ceria−zirconia mixed oxides increased slightly w...
