Product Description

Lanthanum Cerium Oxide

Lanthanum and cerium oxide is a mixture of lanthanum and cerium oxide, usually made by mixing lanthanum and cerium oxide in a certain proportion. It is an important rare earth metal oxide with many important applications. Its formula is usually written as (La_1-x Ce_x) O_2-x/2, where 0 < x < 1 represents the molar fraction of lanthanum oxide and cerium oxide in lanthanum and cerium oxide. First, it is a good oxidizing agent and is often used in areas such as catalysts and spark plugs. Secondly, it is also widely used in solid oxide fuel cells (SOFC). In addition, lanthanum and cerium oxide is often used in ceramic and glass materials. Other applications include catalysts, waste gas treatment catalysts.

Application
Lanthanum cerium oxide (La-Ce oxide), as a composite oxide of lanthanum and cerium, combines the characteristics of two rare earth elements and shows synergistic effects in multiple fields:
1. Catalysis and environmental protection field
- Exhaust gas purification and catalytic reaction
Cerium oxide (CeO₂) is the core component of the three-way catalyst (TWC) and is used to purify CO, NO_x and hydrocarbons in automobile exhaust. .

- Wastewater and exhaust gas treatment
The adsorption performance of cerium oxide can be used to remove heavy metals and radioactive substances in water, while the chemical activity of lanthanum oxide may synergistically enhance the capture ability of pollutants. In addition, the composite oxide of the two also has potential in exhaust gas treatment processes such as desulfurization and denitrification.

2. Functional materials and electronic devices
- Optical glass and ceramic additives
Lanthanum oxide is used to improve the refractive index of glass and the heat resistance of ceramics, while cerium oxide is used for glass decolorization and polishing. The combination of the two may optimize the light transmittance, mechanical strength and high temperature resistance of optical materials, and is suitable for precision optical devices and special ceramics.

- Solid Oxide Fuel Cell (SOFC)
Both lanthanum oxide and cerium oxide can be used as electrolyte or electrode materials. For example, cerium-based electrolytes (such as cerium oxide doped with lanthanum oxide) have high oxygen ion conductivity and are suitable for medium and low temperature fuel cells to improve energy conversion efficiency.

3. Energy and Electronic Technology
- Energy Storage and Battery Materials
Cerium oxide can inhibit the structural collapse of electrode materials in lithium-ion batteries, while the doping of lanthanum oxide may further improve the cycle stability of batteries and is suitable for new energy storage systems.
