摘要： A method for extracting uranium with a coupling device of wind power generation and uranium extraction from seawater includes the following steps: adding oxygen vacancy (OV)-containing In2O3-x to absolute ethanol, and subjecting a resulting mixture to stirring and ultrasonic treatment to obtain a solution of In2O3-x in absolute ethanol; coating the solution uniformly on carbon cloth, and drying to obtain carbon cloth coated with OV-containing In2O3-x; inserting the coated carbon cloth (as a working electrode) and another blank carbon cloth (as a counter electrode) into a plastic carrier of a coupling device; fixing a small wind power generation apparatus above the plastic carrier, and connecting the working electrode and the counter electrode to a storage battery of the apparatus via wires; and placing the coupling device in seawater, and after the storage battery is charged, energizing the working electrode and the counter electrode to extract uranium from the seawater.
