"Cerium oxide" refers to a chemical compound made up of the elements cerium and oxygen. It is commonly used as a polishing agent and can also be found in various industrial applications, such as catalysts and glass manufacturing. Full definition
Incorporation of CNTs enhanced electron flow associated with photosynthesis by 49 % in extracted chloroplasts and by 30 % in leaves of living plants, and incorporation of cerium oxide nanoparticles (nanoceria) into extracted chloroplasts significantly reduced concentrations of superoxide, a compound that is toxic to plants.

The goal is to get cerium oxide clusters as small as a single cerium atom with two oxygens. (pnnl.gov)
In the catalytic converter, the catalyst cerium oxide grabs oxygen from air and adds it to carbon monoxide and hydrocarbons to turn them into carbon dioxide, which is nonlethal. (sciencedaily.com)
