  • Photocatalytic deposition of metals and compositions comprising the same
    Patent number: 8143185
    Abstract: A photocatalytic metal deposition process and a resulting nanocomposite are described. The nanocomposite includes an electrically conducting carbonaceous material, a photoactive metal oxide and a metal. Metals for deposition include noble metals, metal alloys and other transition metals in which the metal is laid down precisely and in a predetermined fashion on one or more surfaces of a composite. Deposition provides a high performance electrocatalyst for a number of suitable applications.

  • COMBUSTION SYNTHESIS AND DOPING OF OXIDE SEMICONDUCTORS
    Publication number: 20090311169
    Abstract: The present invention relates to a method for producing inorganic oxide particles from a precursor material or mixture under combustion synthesis and compositions thereof. The combustion synthesis method is low-cost, low tech, and energy efficient. The combustion synthesized inorganic oxide particles of the method are smaller and exhibits a lower band gap than commercially available specimen of the same chemical composition.
