[2], Cerium occurs naturally as a mixture with other rare-earth elements in its principal ores bastnaesite and monazite. Ceria has been explored towards the catalysis of various hydrocarbon conversion reactions including CO2 methanation and the catalytic oxidation of hydrocarbons such as toluene. Considering these two findings, Ce 2 O nanoparticles show potential for antibacterial coatings in several substrates. When there is a shortage of oxygen, cerium(IV) oxide is reduced by carbon monoxide to cerium(III) oxide: When there is an oxygen surplus, the process is reversed and cerium(III) oxide is oxidized to cerium(IV) oxide: Major automotive applications for cerium(III) oxide are, as a catalytic converter for the oxidation of CO and NOx emissions in the exhaust gases from motor vehicles,[1][2] and secondly, cerium oxide finds use as a fuel additive to diesel fuels, which results in increased fuel efficiency and decreased hydrocarbon derived particulate matter emissions,[3] however the health effects of the cerium oxide bearing engine exhaust is a point of study and dispute. Cerium oxide is an all-purpose lapidary polish that can be used on wheels and flat laps covered with leather, felt, canvass or other popular coverings.
