Abstract

The invention discloses a preparation method of a submicron hydroxy zinc stannate cube, the size of which is 100-300 nanometers. According to the preparation method, raw materials, including cetyl trimethyl ammonium bromide, n hexanol, cyclohexane and deionized water, are selected to form a microemulsion; the microemulsion reacts with zinc sulfate and sodium stannate which are used as reactants to respectively prepare a microemulsion containing zinc sulfate and a microemulsion containing sodium stannate; the two microemulsions are mixed to react and undergo aging, centrifugation, washing and drying so as to obtain submicron hydroxy zinc stannate cubic particles, which can be used as photocatalysis, gas-sensitive and flame retardation materials and the like. The method can be adopted to synthesize the size-controllable hydroxy zinc stannate cubic material at room temperature. The production technology is simple, requires low cost and causes no environmental pollution.

Description

technical field [0001] The invention relates to a method for preparing a submicron hydroxyzinc stannate cubic material by using a microemulsion method, and belongs to the technical field of inorganic advanced nanometer material preparation technology. Background technique [0002] The continuous growth of global energy consumption and the relative shortage of traditional fossil energy have exacerbated the greenhouse effect and brought about environmental pollution problems. The increasingly serious environmental pollution has become a significant problem restricting economic development and affecting people's daily life, and has attracted widespread attention. How to effectively deal with energy crisis and environmental pollution, which hinder the sustainable development of human society, has become an urgent global research topic. The most critical and basic way to solve and cope with energy shortage and environmental pollution is to design and prepare functional materials...
