The invention discloses a preparation method of Mn-doped copper slag-based geopolymer derived hollow porous microspheres, which is characterized by comprising the following steps: adding manganese salt and copper slag powder into an oxalic acid solution, uniformly mixing to obtain slurry, dropwise adding the slurry into dimethyl silicone oil under a stirring condition, balling under the action of stirring mechanical force, and aging the mixture at 55-65 DEG C for 12 hours to obtain the Mn-doped copper slag-based geopolymer derived hollow porous microspheres. Carrying out solid-liquid separation, and calcining the solid at 550-650 DEG C to obtain Mn-doped copper slag-based geopolymer derived hollow porous microspheres; the prepared catalyst is applied to adsorption-photocatalytic degradation of antibiotics, the experimental result shows that the material has good adsorption-photocatalytic degradation performance on the antibiotics, the catalyst has magnetism and is easy to separate, recover and reuse, the comp
