Abstract The present invention relates to a new load-type cyclopentadienyl metal catalyst and its application. The carrier uses montmorilonite, bowlingite, lithium montmorillonite, synthetic mica and sepiolite as raw materials through treatment with amine salt and amino acid to form nanometer material with specific surface area 640 sq.m./g-100 sq.m./g. Due to the use of nanometer material as carrier, it raises the load rate of catalyst, and reduces the quantity of cocatalyst used. The invented catalyst is suitable for the polymerization of olefin hydrocarbon.
