The invention belongs to the field of novel catalysts and discloses a preparation method of a bismuth oxide (Bi 2 O 3 ) photocatalyst with a two-dimensional structure. It includes the following steps: (1) preparing an ethanol/ethylene glycol solution of P123; (2) adding bismuth nitrate to complete dissolution, then adding a certain amount of oxalic acid to adjust the pH value, and magnetic stirring; (3) solvothermal reaction, After washing, centrifugation and drying, a two-dimensional structured bismuth oxide photocatalyst is obtained. The preparation method is simple, the cost is low, and the product has high purity, uniform appearance, good dispersibility and stable performance. The two-dimensional structure bismuth oxide nanosheet prepared by the invention has high solar energy utilization rate, high quantum efficiency and high photocatalytic activity, and can be applied to catalyze the degradation of organic pollutants in the environmental field. |
