  • Patent number: 9555406
    Abstract: A method for forming an oxide coated substrate comprising heating a pre-coating mixture in the presence of a substrate to synthesize an oxide coating on the substrate. The pre-coating mixture comprises a solubilized reducing additive, a solubilized oxidizing additive, and the substrate. The heating is conducted at a temperature sufficiently high enough to exothermically react the solubilized reducing additive and solubilized oxidizing additive and low enough to control the phase and composition of the oxide.

  • Patent number: 9522389
    Abstract: Photocatalytic materials are described herein which include thin nanostructures. For example, the catalytic material can include a nanostructure that has a thin structure of a photocatalytic composition, wherein the thin structure is defined by a first surface and a second surface on opposite sides of the thin structure of the photocatalytic composition. The photocatalytic composition may include an inorganic compound, such as a titanium and/or stannous oxide. The first surface and a second surface may be relatively large as compared to the thickness of the thin structure, or the thickness of the nanostructure.
