The invention discloses a heteropolyacid material constructed by a Dawson type polyacid and a six-core copper complex, and a preparation method and application thereof. The hybrid material is prepared from Na2WO4.2H2O, CuCl2.2H2O, H3PO4, 1,10-phenanthroline (or 2,2'-biyridine) and H2O by a hydrothermal method. The material is used for degrading methyl orange, methyl blue, rose color, Congo red or an organic dye which has the same chromophore as the organic dye. The hybrid material has the advantages of maintaining the photo-catalytic activity of the heteropolyacid for degrading the organic dye, overcoming the defects of easy dissolution of the polyacid in a polar solvent, difficult treatment of organic dye-containing wastewater and difficult recovery, also overcoming the defect that the heteropolyacid can only generally show photo-catalysis in ultraviolet light and having extremely high photo-catalytic activity even at a visible region, along with obvious absorption effect at the visible ...
