Abstract
TPPR and XPS characterizations were combined to study the reaction mechanism of CO 2-reforming of methane to syngas over Co/γ-Al 2-O 3 catalysts. CO 2 shows a tendency to form surface carbons by deep dissociation at high temperatures. CO 2 dissociation reaction also occurs at >673K. It is believed that carbide carbons are active species to generate CO by reacting with O atoms dissociated from CO 2. In the reaction, Co (0) particles are responsible for dissociating CH, to form active C, abstracting an O atom from CO 2 molecule, and transferring O atom to C to form CO.
