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.
An interface on a plasma generated particle for pinning nano-active material to a nano-support comprising a compound configured to limit movement of the nano-active material on a surface of the nano-support, wherein the nano-support comprises a partially reduced alumina surface and wherein the compound is formed by a reaction of the nano-active material and the surface of the nano-support, and the movement to be limited is based on physical movement of the nano-active material from one site on the surface to another site on the surface.
A pinning method to affix nano-active materials to nano-supports by using a high temperature condensation technology comprising:
A method of affixing a nano-active material to a nano-support comprising using high temperature condensation technology to form a layer between the nano-active material and the nano-support material on a plasma generated particle and increasing metallic content on surfaces of the nano-supports by reducing the nano support material so that movement of the nano-active material on a surface of the nano-support is limited and the movement to be limited is based on physical movement of the nano-active material from one site on the surface to another site on the surface.
