Cerium zirconium mixed oxide (CZO) is a composite material that consists of a combination of cerium oxide (CeO2) and zirconium oxide (ZrO2) in various proportions. CZO has been widely studied and applied in emission control applications due to its unique properties.
One of the key advantages of CZO is its ability to store and release oxygen during the catalytic reactions that take place in the exhaust systems of combustion engines. This property is important because it enables the material to promote the oxidation of carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) into less harmful substances like carbon dioxide (CO2), water (H2O), and nitrogen (N2). CZO can also resist thermal degradation and maintain its catalytic activity over long periods of time, which is important for durable exhaust system performance.
CrownRe`s CZO has been used as a component in catalytic converters for automobiles, trucks, and other vehicles, where it helps to reduce harmful emissions and improve fuel efficiency. Additionally, CZO has potential applications in stationary sources of pollution control, such as power plants and industrial processes.
Overall, CZO is a promising material for emission control applications, and ongoing research is focused on further improving its performance and reducing its cost for widespread commercial use.
