The invention discloses a photocatalytic oil-water separation omentum, a preparation method and application thereof. In the preparation method, firstly, the copper mesh is ultrasonically cleaned with dilute hydrochloric acid, absolute ethanol and deionized water, and then blown dry with nitrogen; the tungstate solution is used as the electrolyte, the cleaned copper mesh is used as the anode, and the inert electrode is used as the cathode. , so that the anode and cathode are connected to the positive and negative poles of the power supply respectively, and the anodic oxidation method is used to conduct constant current electrolysis or constant voltage electrolysis. After the electrolysis is completed, the anode is washed with deionized water and dried to obtain cuprous oxide/tungsten Copper mesh covered by acid copper composite film layer. The omentum has superhydrophilicity and underwater superoleophobicity, and can efficiently separate oil-water mixtures. The present invention utilizes the p-n junction structure of cuprous oxide/copper tungstate to photocatalytically degrade organic pollutants in water under visible light to achieve oil-containing and Separation and purification of organic pollutant wastewater. The preparation process of the invention is simple, the raw materials are environment-friendly and the cost is low. |
