Cerium oxide-based materials refer to compounds and compositions that incorporate cerium oxide (CeO2) as a primary component. Cerium oxide is a white, amorphous, and high-temperature stable oxide of cerium, a rare earth metal. It is widely used in various applications due to its unique properties, including its ability to act as a catalyst, oxygen storage capacity, and resistance to high temperatures.

One of the most common applications of cerium oxide-based materials is in the field of catalysis. Cerium oxide is used as a catalyst in various chemical reactions, such as the water-gas shift reaction, which is crucial in the production of hydrogen. It is also used in the catalytic conversion of hydrocarbons and in the removal of pollutants from exhaust gases.

Cerium oxide-based materials are also used in the field of materials science. They are used as a dopant in various materials to improve their properties, such as conductivity and stability. For example, cerium oxide is used as a dopant in zirconia to improve its oxygen ion conductivity, making it suitable for use in solid oxide fuel cells.

In the field of medicine, cerium oxide-based materials are used in the development of drug delivery systems. Cerium oxide nanoparticles are used to encapsulate and deliver drugs to specific sites in the body, improving the efficacy and reducing the side effects of the drugs.

Cerium oxide-based materials are also used in the field of environmental remediation. They are used to remove heavy metals and other pollutants from water and soil. Cerium oxide nanoparticles are used to adsorb and remove pollutants from water, while cerium oxide-based catalysts are used to degrade organic pollutants in soil.

In summary, cerium oxide-based materials are versatile and have a wide range of applications in various fields, including catalysis, materials science, medicine, and environmental remediation. Their unique properties make them an important component in many modern technologies and products.
