The invention discloses a preparation method of europium-doped zinc oxide photocatalyst, which comprises dissolving zinc acetate in absolute ethanol, adding NaOH and europium nitrate, and stirring for 1 hour to obtain a uniform mixed solution; Put it into a polytetrafluoroethylene-lined reaction kettle, react at 180°C for 5 hours, and then cool to obtain the product; wash the obtained product with absolute ethanol and water, centrifuge three times, and dry at 70°C 12h, and then put it into a muffle furnace for sintering at 800°C for 1h to obtain the europium-doped zinc oxide photocatalyst material. The europium-doped zinc oxide photocatalyst provided by the invention has relatively high photocatalytic activity, and after repeated use, the europium-doped zinc oxide catalyst still has relatively high photocatalytic activity. |
