As good as new : Perovskite‐based catalysts containing Rh and Pt for use in exhaust‐emissions control systems are developed. These catalysts are found to be self‐regenerating and could thus lead to the use of lower amounts of precious metals. The picture shows the TEM image of Pt grains of catalyst CaTi 0.95 Pt 0.05 O 3 aged in an engine exhaust at 900 °C for 100 h.
