Claim 20:
21. A method of producing metal oxide compounds by high-temperature molten salt electrolysis in humid atmosphere, wherein the method is carried out in a humid molten salt electrolysis environment, solid metal oxide cathodes are reduced in-situ by hydrogen generated through electrolysis in the molten salt, during the electrolysis, the metal oxides are used as working cathodes, and corresponding metal oxide compounds are prepared; and the temperature of the molten salt is 150 to 1000° C., the water vapor content of a protective atmosphere of the molten salt is 0.1 to 100 Vol. %, and the molten salt electrolyte is one or more of LiF, LiCl, LiBr, LiI, NaF, NaCl, NaBr, NaI, KF, KCl, KBr, KI, RbF, RbCl, RbBr, RbI, CsF, CsCl, CsBr, CsI, MgCl2, MgF2, CaCl2, CaF2, SrCl2, SrF2, BaCl2, BaF2 and ZnCl2.
