英文摘要	Cu-Ce based catalysts is an important type of catalyst due to its high activity, and the exploration of Cu-Ce synergistic effect is always on the focus. This study provides a new insight into the synergistic effect between copper and cerium based the toluene combustion properties over CuCeOx catalysts prepared with different methods. The catalyst synthesized by sol-gel method exhibits the best synergistic effect, and post calcination of the physically mixed catalyst can strengthen the formation of Cu-O-Ce solid solution. Under low temperature conditions (TT-50). The lattice oxygen in the Cu-O-Ce bond is active under relative high temperature, owing that lattice distortion weakens the metal oxygen bond, making it easier to participate in reaction or transfer from bulk phase to catalyst surface.
