| Abstract: | The necessity and possibility of replacement of noble metals by rare earth elements in the automobile exhaust catalyst control technology were elucidated. The type and the component of three way catalysts (TWC), the role of rare earth elements in TWC, the application prospect of rare earth containing TWC and their market potential were presented. It is indicated that development and the commercialization of rare earth containing three way catalysts are advantageous to find a way out of the harsh difficulty of atmospheric pollution in our country and to make a change from domestic RE conventional Industry to RE high tech. trade. |
