#$%^&*AU2020102258A420201029.pdf#####Abstract The present invention provides a mixed crystal TiO 2/BiOBr composite and a preparation method and application thereof, and relates to the technical field of nano material preparation. Wherein, TiO2 is a mixed crystal structure of a rutile phase and an anatase phase, and BiOBr is a two-dimensional sheet structure, where the two form a heterojunction structure. The present invention achieves effective degradation of organic pollutants by synthesizing a mixed crystal TiO 2 and BiOBr composite (A&R TiO 2/BiOBr) with a specific ratio of anatase phase/rutile phase, constructing a mixed crystal TiO 2 structure with high catalytic efficiency, and forming a heterojunction photocatalytic system with two-dimensional BiOBr, thus providing good practical application value.1/3 Drawings FIG.1
