摘要:
A microstructure that can develop non-conventional and novel physical properties and a method for producing the same are provided. Ethanol is added to a mixture solution produced by adding a surfactant solution to a peroxotitanic acid aqueous solution to produce precipitates, and the precipitates collected from the mixture solution are let dried to produce precursor powders 5. The precursor powders 5 are calcined at a predetermined temperature. Accordingly, a microstructure 2 can be produced which is formed of monophasic Ti4O7 in nano size. The microstructure 2 of monophasic Ti4O7 produced in this fashion can be fine-grained in nano size unlike prior-art crystals.

摘要:
A divalent copper salt and/or trivalent iron salt is supported on a surface of a metal ion-doped titanium oxide obtained by doping titanium oxide with metal ions to give a metal ion-doped titanium oxide with a valence band potential of 3 V or more (vs. SHE, pH=0) and a bandgap of 3 V or less between the valence band and an energy level of electrons excited from the valence band (including conduction band minimum potential and isolated potential). The metal ion-doped titanium oxide can be made to exhibit strong oxidative decomposition activity when irradiated with visible light based on the fact the divalent copper salt or trivalent iron salt functions as a catalyst for multi-electron reduction of oxygen.
摘要:
This invention provides a photocatalyst material, which can be produced at low cost without using platinum, particularly a visible light response-type photocatalyst material, a material having a photocatalyst mechanism not possessed by the conventional photocatalyst material, a process for producing the material, and a method for decomposing a contaminant using the material. The photocatalyst material comprises a) an oxide of a first metal and b) an aqua complex salt of a second metal. In this case, for the oxide of a first metal, the redox potential of a conduction band lower end in the oxide is on a rather negative side than 0.2 V (a value as measured at pH=0, vs. reference electrode potential). For the aqua complex salt of a second metal, the redox potential of a second metal ion in the aqua complex salt is on a rather negative side than 3.0 V (a value as measured at pH=0, vs. reference electrode potential). In the material, the aqua complex salt of a second metal is chemically adsorbed on the oxide of a first metal.
