A method for the production and self-organization of binary and ternary oxy / hydroxides particles

摘要

A method for preparing a homogeneous nano binary or - ternary ldh - metaloxy / hydroxide with a large surface area and 1 – 10 nm particle size according to an aerogel method, the hydrolysis of metal alkoxides or metal in a solvent mixture which is selected from alcohols and hydrocarbons, by means of the controlled addition of deionized water or a mixture thereof with alcohols, 6 to 16 hours ageing, followed by a hydrothermal treatment and, finally, the supercritical drying to obtain a free-flowing powder consisting of a homogeneous nano binary or - ternary ldh - metaloxy / hydroxide comprises.
