We report a simple method for tuning catalytic propertyof a metallocene-based catalyst, Cp2ZrCl2, for ethylene polymerization by the direct adsorption Of Cp2ZrCl2 onto multi-walled carbon nanotubes (MWCNTs). The direct interactions between MWCNTs and the Cp rings of Cp2ZrCl2 controlled the polymerization behaviors, and we could generate polyethylene with an extremely high molecular weight ((M) over bar (W) = 1000000) at 30 degrees C and under 1 atm of ethylene gas.
