A catalyst was prepared by supporting polymer catalysts onto a named nano three pore mesoporous materials composed of pure silica and KIT-6, and its activity for catalyzing ethylene polymerization was evaluated. The sample was characterized by means of XRD， SEM and N<sub>2</sub> adsorption-desorption. SEM and XRD results show that the sample are in sphere shape with three dimentional channel structure. N<sub>2 </sub>adsorption-desorption results show that the sample have the five physisorption isotherms and pore distributions are three pores and uniform. The experimental results showed that the sample had high activities for catalyzing ethylene homo-polymerization.
