AB - This study reports the performance of a self‐regenerating perovskite, LaFeCoPdO3 as a three‐way catalyst (TWC) and its use for self‐diagnostic by means of integrated Al‐doped TiO2 and LaFeCoPdO3 sensor arrays, consisted of semiconducting oxides as sensing layers and LaFeCoPdO3 as catalytic filter. Although perovskite catalyst yields a reasonable NO conversion performance at lower temperatures, it cannot fully compete with a commercial TWC under the TWC relevant temperatures and conditions. On the other hand, as‐coated duplex layer exhibits reasonable sensor property toward NO2 at 600 °C but sensor response deteriorates in NO2 + CO mixed gas environment. Ageing tests in the harsh exhaust peripherals however yield that perovskite improves the duplex layer's response through crack network and by protecting semiconducting oxide.
