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 .
