Preparation method of metal compound nano-structure thin-film material

The invention discloses a preparation method of a metal compound nano-structure thin-film material. The method comprises the following steps: preparing a solution from a strong acidic-weak basic metal salt with hydrolysis ability; putting the solution into a metal substrate which is cleaned in advance; and inducing continuous hydrolysis reaction of metal ions through the metal substrate at a hydrolysis reaction temperature of the metal ions to prepare a multi-metal compound nano-structure thin-film material. The thin-film material can be taken as an electrode material directly or through thermal treatment. According to the preparation method of the metal compound nano-structure thin-film material, a nano-structure thin film can efficiently grow on the surface of the metal substrate through continuous directional self-assembly; the synthesis technology is simple; any strong acid, strong alkali or strong oxidant does not need to be used in the reaction process; the method is environment-friendly; the reaction c
