| Abstract: | In this Paper,recent advances of the chromium\|based catalysts developed,at home and abroad,were reviewed.From the incisive analysis based on the documents collected,and a longstanding debate over questions about chemical nature of the active site(s),the oxidation state of active chromium,and the mechanism of initiation has been resoluted,it was concluded that chromium\|based catalysts would continue to play an important role in ethylene industry and take up some fields in nanocomposite materials in coming years. |
