Title:
COPPER NANO-FILM LOADED ON BASE MATERIAL AND PREPARATION METHOD AND APPLCIATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/107998
Kind Code:
A1
Abstract:
A preparation method for a copper nano-film loaded on a base material comprises: mixing a cupric salt solution and a chelating agent, slowly adding a first alkaline solution while vigorously stirring, thus obtaining a chelate solution; adding a reducing agent in the chelate solution and then stirring, and then transferring the obtained solution to a reaction kettle; rolling a base material into a cylindrical form that adheres closely to the inner wall of the reaction kettle, reacting for 1-8 hours at the temperature of 100-180°C so that nano copper is evenly deposited on the base material after reaction. Also disclosed are a film prepared by the described method and application of the film for catalyzing reduction of p-nitrophenol with hydrazine hydrate. According to the described method, the reducing rate of copper salt is controlled through complexing of the chelating agent and the cupric salts to obtain the copper film composed of nanosheets; and the copper nanosheets are successfully loaded on the two-dimensional base material through a one-step synthesis method.
