1. a ZnFe 2o 4the preparation method of/BiOBr magnetic photocatalyst, is characterized in that, comprises the following steps:

  • A. by ZnCl 2and FeCl 36H 2o is that the ratio of 1;

    0.5-3 is dissolved in ethylene glycol solution with mol ratio, stirs, obtains solution A;

    B. NaAc and polyethylene glycol are added described solution A, stir, obtain solution B;

    C. be transferred in reactor by described solution B, heating is obtained by reacting solution C and precipitation D;

    D. be separated described solution C and described precipitation D, and wash described precipitation D, dry, described precipitation D is ZnFe 2o 4;

    E. by Bi (NO 3) 35H 2o and described precipitation D is that the ratio of 1;

    0.6-1.2 is dissolved in acetum with mol ratio, stirs, obtains solution E;

    F. by KBr with 2 times to described precipitation D mol ratio, join in described solution E, stir, room temperature ageing, obtain solution F and precipitation G;

    G. described solution F and described precipitation G is separated, washing precipitation G, dry, obtain ZnFe 2o 4/ BiOBr catalysis material.
