Full spectrum photocatalytic air purification solution and preparation method thereof

The invention relates to a full spectrum photocatalytic air purification solution and a preparation method thereof. The method includes: according to the formula requirements, subjecting tungsten oxide, copper oxide, iron oxide and titanium oxide to pulping in deionized water, and mixing the substances evenly, then adding a dispersion stabilizer and stirring the substances evenly, adding a pH regulator to adjust the pH within the range of 5-8, conducting sanding or high speed dispersion and other dispersion means to form a stable suspension, thus obtaining the full spectrum photocatalytic airpurification solution with dispersion stability. The photocatalytic air purification solution prepared according to the invention can absorb full spectrum visible and ultraviolet light with a wavelength of less than 730nm, and the photocatalyst dispersion solution is white or grey white in appearance and color. The full spectrum photocatalytic air purification solution provided by the invention has the advantages of safe
