METAL COMPOSITE, PHOTOCATALYST SUPPORT, POROUS ELECTRODE, PHOTOCATALYST ELECTRODE, PHOTOELECTRIC CONVERSION ELEMENT AND DYE-SENSITIZED SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a metal composite that has an excellent function as an electrode or a photocatalyst support.SOLUTION: The metal composite has a tungsten substrate, and a titanium layer covering a portion or all of the surface of the tungsten substrate, the titanium layer being preferably a sputtered film, the metal composite being preferably in any of the shape of a punched metal shape, a mesh shape, a lattice shape or a particle-sintered body shape. The metal composite is used in photocatalyst support, photocatalyst electrode, a photoelectric conversion element or a porous electrode of a dye-sensitized solar cell, or the like.SELECTED DRAWING: None
