FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Cerium oxide CeO2 nanoparticles are obtained by mixing 0.2 M Ce(NO3)3 · 6H2O solution with supercritical water. The reaction is carried out at temperature of 370-390°C and pressure of 240-260 atm. The ratio of the volume of the cerium salt solution to the volume of supercritical water is preferably equal to 2:10.
EFFECT: synthesis of metal oxide nanoparticles and creating an ecologically clean, wasteless technology.
