Co3O4/CeO2 composites with high surface areas and ultrafine crystalline sizes for catalytic combustion of methane were firstly prepared by a new sol-gel method which combined ultrasonic impregnation treatment and calcination in N2 atmosphere. The samples were characterized by various means such as n...
