| Abstract: | Palladium-based catalysts have been developed for the diesel exhaust system with an emphasis on their sulphur tolerance during the simultaneous oxidation of CO and HC. Promising materials include Au–Pd–Pt, Co–Pd–Pt and Ni–Pd–Pt supported on Al2O3 or TiO2 and Pd–Pt/MoO3–Al2O3 with the Al2O3 support modified with MoO3 monolayer. |
