Patent ID: 7306824

Claim:
A method for preparing a metal nanocluster composite material, comprising: treating a porous zeolitic material with an aqueous metal compound solution to form a metal ion-exchanged zeolitic material; heating said metal ion-exchanged zeolitic material at a temperature ramp rate of less than 2° C./min to an elevated temperature less than 400° C.; cooling said metal ion-exchanged zeolitic material to a temperature less than approximately 80° C.; contacting said metal ion-exchanged zeolitic material with an organic monomer capable of undergoing polymerization; removing air from said metal ion-exchanged zeolitic material using vacuum treatment to allow said monomer to penetrate said porous zeolitic material to form a metal ion-exchanged zeolitic material and monomer composite material; inducing polymerization of said monomer by heating said composite material to form a polymer composite material; and heating said polymer composite material to a temperature greater than 350° C. under non-oxidizing conditions to form a metal nanocluster-carbon composite material.
