The invention relates to a seawater ecological environment restoration material, which is characterized in that the preparation process of the material is as follows: (1) Bi(NO3) 3 , Na2WO4 ยท 2H2O, cerium nitrate, cyclohexamethylenetetramine The amine is added to the ethylene glycol solution, stirred and dissolved, then the ammonia solution is added dropwise, the pH is adjusted to 7-9, the mixed solution is transferred to the autoclave, and the solvothermal reaction is carried out at 200-220 degrees Celsius for 13-20 h to obtain a dandelion-like shape the Ce-doped Bi 2 WO 6 ; (2) dissolving zinc acetate and thiourea in deionized water under stirring, then adding the dandelion-shaped Ce-doped Bi 2 WO 6 prepared in step (2), after 300- The 500w xenon lamp was irradiated for a certain period of time, and then the Ce-doped Bi 2 WO 6 /ZnS composite material was obtained after washing and drying. |
