摘要：

A new catalyst CeO2-ZrO2-Bi2O3 on La-stabilized,gamma-Al2O3 is prepared for advanced catalytic converters. The low-temperature redox activity of the catalyst (see figure), which is effective below 100 degrees C. has, to date, never been attained in conventional catalysts without help of precious metals.
