摘要

Automobile exhaust has become one of the main sources of atmospheric pollution. Currently catalyststhat meet the Euro and above emission standard generally consist of two parts: Three Ⅳ -Way Catalysts (TWC) and Close-Coupled Catalysts (CCC). The CCC mainly oxide the hydrocarbon (HC) of the cold start emissions, because the cold start HC emissions accounted for 60%-80% of the entire operation. The γ-Al2O3 is widely used as the support of the Close-Coupled Catalysts. It is reported that Ce, Zr are able to stabilize alumina at the high temperature, and they can keep the alumina with large surface area and pore volume.
