Document Type and Number:
Japanese Patent JP7411982
Kind Code:
B2
Abstract:
To provide a composite material capable of functioning as a catalyst and effectively photoreducing carbon dioxide.SOLUTION: There is provided a metal oxide-containing composite containing: particles of a metal oxide containing two or more kinds of metals classified into groups 6 to 12 in the periodic table; and a carrier carrying the particles of the metal oxide, wherein the metal oxide forms a spinel crystal structure and a perovskite crystal structure and has an average particle size of metal oxide particles of 5 nm or less. The metal oxide is a metal oxide-containing composite which is CuCo2O4, MnCo2O4, or FeCo2O4. The carrier is a metal oxide-containing composite which is a particle of TiO2, SnO2, Al2O3, PbO2, or ZnO. There is also provided a method for producing a metal oxide-containing composite including the steps of: mixing a first solution and a second solution, which are emulsions containing water-in-oil micelles; adding the carrier to the mixed solution; adding a water-soluble organic solvent to the mixed solution; taking out an insoluble matter containing the carrier from the mixed solution; and sintering the insoluble matter.SELECTED DRAWING: Figure 1
