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.

It is an object of the present invention to provide a microbial fuel cell capable of increasing a current density without employing a mediator. The microbial fuel cell 1 includes a 3-dimensionally structured agglomerate formed from conductive fine particles 2 and microorganisms 3. In the agglomerate 4, the conductive fine particles 2 disperse among pieces of Shewanella 3 and the conductive fine particles 2 are coupled to one another to hold Shewanella 3, thus forming the 3-dimensional structure as a whole. Accordingly, with respect to Shewanella 3, conductive fine particles 2 hold Shewanella 3a on a surface of an electrode 103 and even Shewanella 3b positioned vertically away from the surface of the electrode 103. Hence, it becomes possible that more pieces of Shewanella 3 are allowed to transfer electrons.

Provided is an edge-light illuminating device in which a deformation is prevented from occurring in a reflection sheet due to thermal expansion of the reflection sheet. An edge-light illuminating device (3) of the present invention is arranged to illuminate a liquid crystal display panel (2) from a back side of the panel, and includes a light guide plate (7), a light source (5) that faces an edge face (72) of the plate and is arranged to project light onto the edge face, a case (4) arranged to house the plate and the light source, and a reflection sheet (6) laid on a bottom face (41) of the case and sandwiched between the bottom face and a back face (71) of the plate housed in the case, wherein the reflection sheet includes a slot portion (61) disposed along a direction that the reflection sheet expands by heat generated by the light source.

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.
