1.Brief introduction
The rare-earth elements (REE) are the elements Sc (scandium) Y (yttrium) and the 15 lanthanide elements with atomic numbers 57 through 71, namely, La (lanthanum), Ce (cerium), Pr (praseodymium), Nd (neodymium), Pm (promethium), Sm (samarium), Eu (europium), Gd (gadolinium), Tb (terbium), Dy (dysprosium), Ho (holmium), Er (erbium), Tm (thulium), Yb (ytterbium), and Lu (lutetium).
2.The application of rare-earth
In the traditional industrial field, rare-earth is mainly used in agriculture, metallurgy, petrochemical industry, glass, ceramics and electric light industry. With the research of rare-earth developing, (With the development of the research of rare-earth), rare-earth is gradually applied in high and new technology industry, used as luminescent material in display, magnetic material, hydrogen storage material, laser material, high temperature superconducting material, fine ceramic and catalyst.
3.The application of rare-earth in automotive exhaust gas
With the growth of automotive quantity, the exhaust emission becomes the flowing resource (source)of pollution, which is a serious harm for atmosphere. To deal with the emission exhaust, we generally adopt to fit purifying equipment. The key of the purifying equipment is catalyst. At present, the widely used catalyst is normally composed by noble metal Pd, Pt, Rh. Though this kind of catalyst posses the advantage of high activity, favorable thermal stability, long service life, its cost is expensive. Since put forward of using catalyst with rare-earth in purifying off-gas, its own catalytic capability has attracted all catalyst researchers¡¯ attention. Such kind catalyst has high activity, favorable thermal stability, long service life as noble metal catalyst; and the rare-earth can improve the activity of catalyst, storage and release the oxide, resist the lead poisoning, furthermore, this kind catalyst is not expensive..
Our co***ny freshly have successfully explored rare-earth complex catalyst, which is a reasonable form |
