The invention relates to a preparation method, product and application of a supported C, N, B co-doped titanium dioxide mixed crystal photocatalyst. The hetero-modified TiO 2 mixed crystal is fixed on the carrier, and the open pores and network structure of the carrier are used to improve the dispersibility of the catalyst and increase the contact area between the photocatalyst and organic pollutants. Co-doping can effectively narrow the band gap of the photocatalyst, expand the light absorption range to the visible light region, and promote the removal of organic pollutants in water. In addition, the supported catalyst of the present invention effectively solves the problem of catalyst recycling, which is of great significance for practical application. |
