Abstract

The invention discloses a preparation method of an inorganic nanocomposite FexOy / M. The preparation method includes: mixing precursor solution of M to prepare Fe3O4 nano clusters and proper alkali solution, performing hydrothermal treatment at a certain temperature for a certain time to obtain a product, and separating-cleaning, drying the product to obtain the inorganic nanocomposite FexOy / M; wherein the FexOy is Fe3O4 or Fe2O3, M is one or mixture of two of NiO, BiFeO3, La(OH)3, Cd(OH)2, CuO, and FeOOH. The preparation method is simple, universal, and a huge progress, and breaks through the limit that composite with one component or inorganic nanocomposite with one morphology can be prepared in the prior art. The nanocomposite prepared by the method has application prospect in fields such as nano catalysis, solar energy conversions, lithium ion batteries, and gas sensitive devices.
