  • Patent number: 8778831
    Abstract: There is described a base metal modified Cerium containing oxide materials and their application as catalysts for the oxidation of CO and HC emissions from a compression ignition/diesel engine. These materials provide effective promotion of CO and HC oxidation function in the presence or absence of PGM and are based upon OIC/OS materials having a stable cubic crystal structure, and most especially to promoted OIC/OS materials wherein the promotion is achieved by the post-synthetic introduction of non-precious metals via a basic (alkaline) exchange process.

Both methods utilize a shadow mask technique, wherein the nano-pads are deposited from the catalytic metal source positioned under the angle toward the vertical walls of the opening, so that these walls serve as a shadow mask. In the first case, the vertical walls of the photo-resist around the opening are used as a shadow mask, while in the second case the opening is made in a thin layer of the dielectric layer serving as a shadow mask. Both methods produce the nano-pad areas sufficiently small for the growth of the SWCNT from the catalytic metal balls created after high temperature melting of the nano-pads.

    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.

  • Publication number: 20140088206
    Abstract: The invention relates to improvements in the design of Fischer-Tropsch catalysts comprising a support and cobalt on the support. A first aspect is the modification of the silica support with at least 11 wt % titania to prevent the formation of cobalt silicates, thereby limiting the deactivation resulting from the silicate formation. A second aspect is the provision of C03O4 particles highly dispersed on the catalyst support with an average particle diameter of the cobalt oxide particle of less than 12 nm in order to improve catalytic activity and selectivity.

  • Publication number: 20140080698
    Abstract: A method of making a metal oxide nanoparticle comprising contacting an aqueous solution of a metal salt with an oxidant. The method is safe, environmentally benign, and uses readily available precursors. The size of the nanoparticles, which can be as small as 1 nm or smaller, can be controlled by selecting appropriate conditions. The method is compatible with biologically derived scaffolds, such as virus particles chosen to bind a desired material. The resulting nanoparticles can be porous and provide advantageous properties as a catalyst.

  • Publication number: 20140057779
    Abstract: The present subject matter provides a method of preparing a multicomponent metal-hybrid nanocomposite using co-gasification, in which a multicomponent metal-hybrid nanocomposite can be prepared by a one-step process without using a complicated process including the steps of supporting-drying-calcining-annealing and the like at the time of preparing a conventional alloy catalyst, and provides a multicomponent metal-hybrid nanocomposite prepared by the method. The method is advantageous in that a multicomponent metal-hybrid nanocomposite can be synthesized by a simple process of simultaneously gasifying two kinds of metal precursors, and in that an additional post-treatment process is not required.
