Abstract:
A photo-catalyst comprising a compound having structure composing a network formed by mutual connection of an unit constructing oxygen octahedra or tetrahedra containing a transition metal ion or a typical metallic ion in d10 or d0 configuration and an unit constructing PO4 tetrahedron connected to said oxygen octahedra or tetrahedra, further containing an alkali metal besides said metallic ion as a consituent element, for example, AXNb2mP4O6m+8 (wherein A is Na, K or Li, X is 2, 3 or 4 and m is 3, 3.5 or 4) AXTa2mP4O6m+8 (wherein A is Na, K or Li, X is 2, 3 or 4 and m is 3, 3.5 or 4) AXIn2mP4O6m+8 (wherein A is Na, K or Li, X is 2, 3 or 4 and m is 3, 3.5 or 4) and RuO2 is loaded on the compound. The photo-catalyst can be used for the complete decomposition of water.
