Fe (III)-g-C3N4 catalytic material as well as preparation method and application thereof

The invention belongs to the technical field of preparation of catalytic materials, and relates to a Fe (III)-g-C3N4 catalytic material as well as a preparation method and application thereof. The catalytic material comprises a carrier g-C3N4 and a load Fe (III), and is prepared by grinding and mixing an iron precursor and melamine, calcining, grinding and then centrifugally washing. The raw materials for preparing the Fe (III)-g-C3N4 catalytic material are rich in source, low in price and easy to produce, the Fe (III) activating agent is not prone to failure, and the problem of iron mud accumulation is avoided. Meanwhile, the Fe (III)-g-C3N4/Mn (VII) activated PMS system can be used for efficiently removing organic dye or organic matters which are difficult to degrade. 本发明属于催化材料制备技术领域，涉及一种Fe(Ⅲ)-g-C3N4催化材料及其制备方法和应用。所述催化材料包括载体g-C3N4和负载物Fe(Ⅲ)，通过将铁前驱体和三聚氰胺研磨混合，煅烧、研磨后离心洗涤制备得到。本发明制备Fe(Ⅲ)-g-C3N4催化材料的原料来源丰富、廉价、易于生产，且Fe(Ⅲ)活化剂不易失效、不会产生铁泥积累问题。同时Fe(Ⅲ)-g-C3N4/Mn(Ⅶ)活化PMS体系能够高效去除有机染料或难降解的有机物。
