Abstract

The invention provides a preparation method of a zinc hydroxystannate nanorod array with controllable size. The preparation method comprises the following steps: coating a layer of butyl titanate on the surface of a cleaned zinc sheet, placing into an autoclave filled with a 0.5 mol / L sodium hydroxide solution, conducting constant-temperature heating for 12 hours at 180DEG C, washing the zinc sheet sequentially with absolute ethyl alcohol and deionized water cleanly, and drying for 6-12 hours at 60-100DEG C; placing the zinc sheet into a reaction solution containing urea, potassium stannate and a water-alcohol solution, wherein the concentration of urea is 0.1-1.0 mol / L, the concentration of potassium stannate is 0.01-0.05 mol / L, and the volume of absolute ethyl alcohol in the water-alcohol solution is 30%; conducting constant-temperature heating for 1-12 hours at 60-90DEG C; and collecting the zinc sheet obtained in the reaction, washing the zinc sheet sequentially with absolute ethyl alcohol and deionized water cleanly, and drying for 10 hours at 60DEG C, thus obtaining the final product. The method has the advantages of being simple to operate, mild in experimental conditions, low in energy consumption, free from environmental pollution, capable of being applied in large-scale industrial production and the like.

Description

technical field [0001] The invention relates to a method for preparing an array of inorganic nano functional materials, in particular to a method for preparing a size-controllable zinc hydroxystannate nanorod array. Background technique [0002] Today, environmental pollution and resource shortages have become crucial issues restricting the development of the global economy. Therefore, how to solve environmental pollution and resource shortages that hinder the sustainable development of human society has become a global research topic that people are increasingly concerned about. Designing and preparing high-performance and high-efficiency catalytic, photoelectric, and gas-sensing functional materials and device technologies is the most critical and basic technical approach among all technical approaches to solving and coping with energy crisis and environmental pollution. [0003] Zinc hydroxystannate is a new flame retardant and smoke suppressant developed by the Internati...
