Abstract: Disclosed is a process for producing an anion exchange LDH by removing carbonate ions from a carbonate ion-type LDH that can perform the removal of carbonate ions in a safe, reliable and continuous manner while maintaining crystal shape, crystal structure, and crystallinity. The process for producing an anion exchange layered double hydroxide comprises providing a carbonate ion-type layered double hydroxide (LDH) having a composition represented by general formula: QxR(OH)z(CO3 2-)0.5-y/2(X-)y·nH2O, wherein x is a numerical value in the range of 1.8 = x = 4.2; z is 2(x + 1); y is 0 (zero) at the minimum and is increased to less than 1 when an anion (X-) remains in the compound or when an anion (X-) is partially introduced; Q represents a divalent metal ion; R represents a trivalent metal ion; and n is 2 ± 2, as a starting material, and substituting carbonate ion sites by an anion having a valence of -1 (X-) to increase the y value in the formula to 1 at the maximum. The process is characterized in that, when the starting material is dispersed in an aqueous solution mixed with a salt containing an anion having a valence of -1 (X-) in an amount large enough to substitute the carbonate ion sites to perform substitution, the pH (hydrogen ion exponent) value of the aqueous solution is maintained at more than 4 and less than 7.

Abstract: PROBLEM TO BE SOLVED: To provide a dense, high-quality titania nano-sheet the thickness of which is controlled on a nanometer level by a simple means, to eminently reduce time and expense, and to form an ultra-thin titania sheet which can correspond to an object with a complex shape. SOLUTION: By a process in which a substrate is immersed in a cationic organic polymer solution to adsorb the organic polymer on the surface of the substrate and immersed in a nano-sheet colloidal solution with flaky particles suspended, the flaky particles are adsorbed in a self-assembling manner on the substrate by an electrostatic action. After that, the substrate is subjected to ultrasonic treatment in an alkaline aqueous solution. In this way, the overlapping part of the flaky particles can be removed or reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a thin film consisting of nanosheet monolayer film(s) and use of the thin film obtained thereby.SOLUTION: A method for producing a thin film consisting of nanosheet monolayer film(s) by a spin coat method comprises a step of preparing an organic solvent sol formed by allowing nanosheets obtained by the exfoliation of an inorganic layered substance to be dispersed in an organic solvent; and a step of dropping the organic solvent sol onto a substrate and rotating the substrate using a spin coater. Preferably, the nanosheet size, the organic solvent sol concentration and the spin coater rotation speed are controlled.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem that an ultrathin film made by laminating titania nanosheets and a polymer which is developed by this inventor previously is short of thermal stability, chemical stability and mechanical strength and has a fear of hindering a practical use depending on an application because the polymer is laminated within the thin film due to its role of a binder for the nanosheets, although the ultrathin film has an excellent characteristic such as highly efficient absorption for ultraviolet light. SOLUTION: The titania ultrathin film comprises a multi-layered structure of titania nanosheets consisting of ultrathin particles which are obtained by exfoliating laminar titanium oxide microcrystals and has no polymer interposing layer. By alternately laminating titania nanosheets consisting of ultrathin particles which are obtained by exfoliating laminar titanium oxide microcrystals and a cationic polymer on a substrate from liquid phases, respectively, the multi-layered structure film which is made by the titania ultrathin film and the polymer of interposed layer is once manufactured, but the polymer is removed from the film of the multi-layered structure film by heat treatment or electromagnetic irradiation such as ultraviolet rays and, thereby, the titania ultrathin film is produced.

Abstract: PROBLEM TO BE SOLVED: To provide a catalyst, in particular, a photocatalyst having higher efficiency and higher activity compared with a conventional one by using a layer compound. SOLUTION: The layer reconstructed aggregate features that flake-like particles (nanosheet) obtained by exfoliating the microcrystals of a layer compound are reconstructed into layers with monovalent or polyvalent cations inserted into the layers. The aggregate has a photocatalytic function to produce hydrogen and oxygen or at least hydrogen from water when irradiated with light. The aggregate is obtained by dispersing the flake-like particles obtained by exfoliating the microcrystals of a layer compound to prepare a colloidal solution, mixing the colloidal solution with an aqueous solution containing an excess amount of monovalent or polyvalent cations to deposit the thin particles and the cations into layers.
