  • Patent number: 8845994
    Abstract: An active material of the present invention has fine pores formed in the interlayer of a carbon material capable of exhibiting electrochemical double layer capacitance. The fine pores are formed by forming an oxidized graphite structure combined with oxygen in the interlayer of a part or whole of the carbon material containing soft carbon and then removing a part or whole of oxygen in the interlayer. A method for producing an energy storage active material for use in an electrochemical double layer capacitor comprises pre-treating a carbon material through heat treatment and oxidizing the pre-treated carbon material using an oxidant. The method further comprises reducing the oxidized carbon material through heat treatment. The interlayer distances of an active material for respective steps, measured by a powder X-ray diffraction method, are 0.33˜0.36 nm in the pre-treatment step, 0.5˜2.1 nm in the oxidation step, and 0.34˜0.5 nm in the reduction step.

  • Publication number: 20140256540
    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.

  • Publication number: 20140251795
    Abstract: The instant disclosure relates to a manufacturing method of cathode catalyst, comprising the following steps. Initially, mix an organic medium with an iron-based starting material and a nitrogen-based starting material to form a mixture. Followed by adding a carbon material to the mixture and subsequently executing a heating process to form a solid-state precursor. Then mill the solid-state precursor to form a precursory powder. Successively, calcinate the precursory powder in the presence of NH3 to form a cathode catalyst. The cathode catalyst can reduce the activation energy of hydrogen ion reacting with oxygen to make water. The instant disclosure further provides an ozone-generating device.

  • Publication number: 20140213437
    Abstract: Powder catalysts that comprise particles of chemical compounds of Au and Cu deposited on acid-washed carbon-based supports are effective catalysts in ethyne hydrochlorination to produce vinyl chloride monomers (VCMs). They give a high selectivity and productivity of VCM and decreased amounts of the byproducts of chloroethane, dichloroethane and others. Thiocyanates are used as complexing agents to extend the catalyst lifetime. The activity of the catalyst is enhanced by doping nitrogen atoms into the support.
