The invention provides an amorphous photonic crystal schemochrome material based on black titanium dioxide and silicon dioxide composite and a preparation method of the amorphous photonic crystal schemochrome material. The material component comprises SiO2 amorphous photonic crystal and black TiO2, and the mass ratio of the black TiO2 and the SiO2 amorphous photonic crystal is 1 to (0.1-1). The preparation method comprises the steps that (1) black TiO2 nanoparticle powder is prepared, and SiO2 amorphous photonic crystal microsphere powder is prepared; (2) the black TiO2/ SiO2 materials are prepared, specifically, the SiO2 amorphous photonic crystal microsphere powder and the black TiO2 nanoparticle powder are dissolved in ethanol, ultrasonic dispersion is conducted after stirring, and theproduct is dried. According to the preparation method, the schemochrome is combined with the photocatalysis function, the limitation of preparing non-angle independent color material by absorbing coherent scattering light with carbon black as the back bottom is broken, and the obtained material has the function of photocatalytic degradation of pollutants at the same time.
