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.
