The catalytic properties of ceria nanoparticles are widely used as electrolyte materials, in solid oxide fuel cells, solar cells, for the oxidation of automobile fuels, and as part of the composite material for the oxidation of exhaust gases by tripartite catalysts.

An ozonized water treatment method using nano ceric oxide as a catalyst, which is characterized in that nano cerium dioxide material is added as a catalyst in the ozonized water treatment system to promote the degradation of phenolic organic pollutants.
Ceria(CeO2) nano powder has good mechanical strength and good stability under catalytic ozonation conditions, and the catalytic effect can be well maintained after repeated use, which is beneficial to its practical application.

Nano CeO2 is an efficient and economical photocatalytic component in rare earth materials. It can oxidize and decompose various harmful gases into harmless inorganic substances. It can also decompose many refractory organic substances into inorganic substances such as CO2 and H2O through oxidation reactions. It has good stability under specific conditions, can be reused many times, and the catalytic effect can be well maintained.
