Significant Low-Temperature Redox Activity of Ce0.64Zr0.16Bi0.20O1.90 Supported on γ-Al2O3

Significant Low-Temperature Redox Activity of Ce0.64Zr0.16Bi0.20O1.90 Supported on γ-Al2O3

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