Abstract:
1. A process for the preparation of a manganese oxide-cerium oxide composite, the process comprising the steps of: providing a porous matrix, mixing said porous matrix with a precursor solution containing manganese and cerium ions dissolved therein to form a suspension, triggering the formation of a non-fluid phase which contains manganese and cerium in the interior of said porous matrix, said non-fluid phase being in the form of a gel, separating said porous matrix from a liquid phase containing soluble metals, completing the formation of said gel which contains manganese and cerium in the interior of said porous matrix, heat treating said porous matrix to convert said gel containing manganese and cerium placed therein into a manganese oxide-cerium oxide composite, and isolating said composite from said porous matrix, said manganese oxide-cerium oxide composite having a surface area of not less than 300 m
