The invention relates to a preparation method of an α-type bismuth trioxide magnetic nanometer photocatalyst. The invention uses Co(NO 3 ) 2 ·6H 2 O, Nd(NO 3 ) 2 ·6H 2 O and FeCl 3 ·6H 2 O as raw material and benzyl alcohol as solvent, Co 0.5 Nd 0.5 Fe 2 O 4 magnetic matrix was synthesized by solvothermal method. Then, bismuth subsalicylate was used as bismuth source, ethylene glycol was used as solvent, and solvothermal method was adopted Coated Ni 0.6 Zn 0.4 Fe 2 O 4 magnetic substrate to prepare α-type bismuth trioxide magnetic photocatalyst. Compared with the prior art, the preparation method of the present invention has the advantages of simple process and simple operation, high degradation rate and high utilization rate of the light source during photocatalytic degradation of pollutants, and convenient recycling and reuse. The application of the treatment of polluted wastewater has potential application value and has certain scientific significance for the further exploration of bismuth oxide magnetic photocatalysis. |
