摘要
Abstract
The active site of Ziegler-Natta(Z-N)catalysts has a significant influence on the performance of catalysts and polymers.The study of active site structures,a research hotspot in the field of polyolefin catalysts,will provide an in-depth understanding of the relationship between catalyst structure and performance,as well as the catalytic mechanism.This paper introduced the characterization of the active site and in-situ monitoring of the evolution of the active site structure by various spectroscopic methods.Additionally,the paper reviewed the simulation of the active site structure by means of constructing model catalysts combined with surface analysis,and the density functional theory calculation of the active site structure based on magnesium chloride crystal models.Furthermore,the research directions of active site structures of Z-N catalysts were prospected.关键词
