Cu2Zn1-xMnxSnS4, preparation method and use thereof

Belonging to the technical field of water treatment, the invention relates to Cu2Zn1-xMnxSnS4, a preparation method and use thereof. The preparation method of the Cu2Zn1-xMnxSnS4 provided by the invention comprises: mixing a copper salt, a zinc salt, a manganese salt, a tin salt and thiourea with ethylene glycol, then carrying out reaction to obtain precipitate, washing and drying the precipitate to obtain Cu2Zn1-xMnxSnS4, with the Zn element in the zinc salt and the Mn element in the manganese salt being in a mole ratio of 0.4-0.8:0.2-0.6. The method has the characteristics of simple operation and low cost. In addition, the invention also relates to application of the Cu2Zn1-xMnxSnS4 in preparation of photocatalytic degradation materials and degradation of methyl orange, and the degradation process does not cause secondary pollution. The novel photocatalytic degradation material provides a new idea for treatment of water pollution. 本发明涉及CuZnMnSnS及其制备方法及用途，属于水处理技术领域。本发明的CuZnMnSnS的制备方法，其包括：将铜盐、锌盐、锰盐、锡盐及硫脲与乙二醇混
