Different coating companies have different coating technology and formula, so their requirements on rare earth catalyst are different.

According to to different requirements, we can provide various rare earth catalytic materials:

1. Cerium-Zirconium solid solution complex oxides (Ce-Zr)

2. Alumina base Ce-Zr solid solution complex oxides (Ce-Zr-Al)

3. Alumina with rare earth modification

4. CeO with large specific surface area
