PREPARATION METHOD OF METAL OXIDE FROM METAL HALIDE BY DEHYDRO HALOGENATION WITH BASE AND METAL OXIDE PREPARED THEREFROM

摘要

The present invention relates to a preparation method of metal oxide, and more specifically to a preparation method of metal oxide comprising the steps of : a) dissolving metal halide in a solvent; b) adding and reacting water or metal hydroxide having strong basicity; c) adding base to the reaction solution and then raising a temperature thereof to form the metal oxide -carbon complex; d) stopping the reaction by inputting a large amount of water or metal hydroxide and raising the temperature thereof; and e) obtaining the metal oxide-carbon complex by a separation and a cleaning.
