  • Patent number: 8906337
    Abstract: The present invention relates to a method for preparing graphene using the two-dimensional confined space between the layers of inorganic layered materials. Such method comprises the following steps: mix a soluble salt of a divalent metal ion M2+, a soluble salt of a trivalent metal ion M?3+, a soluble salt of a chain alkyl anion A? and a carbon source molecule C and dissolve them in deionized and CO2-eliminated water to prepare a mixed salt solution; mix the mixed salt solution with an alkali solution under nitrogen protection and subject them to reaction and crystallization under nitrogen, and filter the suspension obtained thereafter and wash the filter cake with deionized water until the pH of the filtrate is 7 to 7.

  • Patent number: 8834982
    Abstract: The invention relates to a carbon nanoring and a method for preparing the same. The carbon nanoring according to the present invention is composed of monolayered or multilayered coaxial carbon rings, wherein the carbon ring has a structure similar to that of a closed ring system formed by graphite sheet being rolled, and each of an axial dimension and a radial dimension of the carbon nanoring is nanoscale with the axial dimension being smaller than the radial dimension. The invention further provides a method for preparing the above carbon nanoring including calcinating in an inert atmosphere or a reducing atmosphere a layered double hydroxides obtained by intercalating a long-chain alkyl anion and a carbon source molecule, growing a carbon nanoring within a confined region between layers under the catalysis of the metal element in layers, and removing the metal and the metal oxide by dissolving in an acid to obtain the carbon nanoring.

  • Publication number: 20080105535
    Abstract: A new photocatalyst, which is high in visible light response, is great in quantum efficiency, and is more excellent in photocatalytic activity, is provided. A composite metal oxide, prepared combining two photocatalytic systems of TiO2 and BiVO4, including elements of Bi, Ti, and Vi as composition elements, can be a photocatalyst having a high activity under visible light. Particularly, BiTiVO6, which is obtained at a compounding ratio of 1:1, can be a photocatalyst having a remarkably high activity under visible light. Moreover, a composite metal oxide expressed by a general formula BiTiMO6 (in the formula, M represents at least one element selected from a group consisting of V, Nb, and Ta) can be a photocatalyst having a high activity under visible light.
