Embodiments of the invention relate to advanced catalysts. Advanced catalysts include honeycomb structures having at least one nanoparticle on the honeycomb structure. The advanced catalyst used in diesel engines is a two-way catalyst. The advanced catalyst used in gas engines is a three-way catalyst. In both the two-way catalyst and the three-way catalyst, the at least one nanoparticle comprises a nanoactive material and a nanosupport. The nanosupport is typically alumina. In the dual catalyst, the nanoactive material is platinum. In the three-way catalyst, the nanoactive material is platinum, palladium, rhodium, or an alloy. The alloy has the properties of platinum, palladium, and rhodium. |
