Embodiment 1

[0022] ①In a 30ml reaction bottle, dissolve 1 part of cadmium salt in 1000 parts of water, then add concentrated ammonia water to form a clear and transparent cadmium complex ion solution, then add 100 parts of n-octanol, 1 part of dodecyl sulfate Na, stir vigorously, and let stand for 2 hours.

[0023] ②Transfer the reaction solution prepared according to step ① into a 50ml polytetrafluoroethylene reactor, and irradiate with pulsed microwave for 3 minutes with a pulsed microwave power of 500w. After the reaction, the reaction kettle is naturally cooled to 60° C., the product is filtered, washed with absolute ethanol and water several times, and vacuum-dried to obtain the cadmium hydroxide nanomaterial.

Abstract

The invention relates to a method for preparing a cadmium hydride nano material by microwaves. In the method, cadmium salt is dissolved in water, the mixture is added with ammonia water or sodium hydroxide to form clear and transparent cadmium complex ion solution, the solution is added with water insoluble fatty alcohol, and a fatty alcohol-water interface system is taken as reaction medium, the microwave irradiation technique is adopted, the microwave power and the reaction time are controlled, surface active agents are added to change the size and the shape of products, and finally the cadmium hydride nano material is prepared. The method has the advantages of simple operation procedure, fast reaction and low cost, and cadmium hydride nano materials prepared by the method can be well applied in the fields such as the packaging and releasing of batteries and drugs and the catalyzing separation, etc.

Description

technical field [0001] The invention relates to a microwave preparation method of cadmium hydroxide nanomaterials, in particular to a method for preparing cadmium hydroxide nanomaterials by using an interface system as a reaction medium and adopting microwave irradiation technology. The invention belongs to the technical field of nanometer material preparation. Background technique [0002] Nanomaterials have attracted great attention because of their unique functions and properties. They play an important role in many fields such as nanoelectronics, magnetism, and optoelectronics. Therefore, the controlled synthesis of nanomaterials has received more and more attention. Pay attention, the preparation methods emerge in endlessly. Among them, interfacial synthesis has the characteristics of spontaneous, fast, and low driving force, and has been well applied, and different reactants are in their own environments, which is conducive to product nucleation and shape control duri...
