    Abstract: A nanoparticle comprises a nano-active material and a nano-support. In some embodiments, the nano-active material is platinum and the nano-support is alumina. Pinning and affixing the nano-active material to the nano-support is achieved by using a high temperature condensation technology. In some embodiments, the high temperature condensation technology is plasma. Typically, a quantity of platinum and a quantity of alumina are loaded into a plasma gun. When the nano-active material bonds with the nano-support, an interface between the nano-active material and the nano-support forms. The interface is a platinum alumina metallic compound, which dramatically changes an ability for the nano-active material to move around on the surface of the nano-support, providing a better bond than that of a wet catalyst. Alternatively, a quantity of carbon is also loaded into the plasma gun. When the nano-active material bonds with the nano-support, the interface formed comprises a platinum copper intermetallic compound, which provides an even stronger bond.

    Abstract: Disclosed are, inter alia, methods of forming coated substrates for use in catalytic converters, as well as washcoat compositions and methods suitable for using in preparation of the coated substrates, and the coated substrates formed thereby, which in some cases use iron-exchanged zeolite particles that provide enhanced performance such as lower light-off temperatures and lower pollutant levels in exhaust gases. The catalytic material is prepared by a plasma-based method, yielding catalytic material with a lower tendency to migrate on support at high temperatures, and thus less prone to catalyst aging after prolonged use. Also disclosed are catalytic converters using the coated substrates, which have favorable properties as compared to catalytic converters using catalysts deposited on substrates using solution chemistry. Also disclosed are exhaust treatment systems, and vehicles, such as diesel vehicles, particularly light-duty diesel vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.
