Problems solved by technology

Therefore, the catalysts prepared by cuprous oxide nanocrystalline cubes and hollow polyhedrons have excellent performance, but the above method is only used for theoretical research in experimental preparation, the reaction conditions are harsh, and the product pollutes the environment, so it is not suitable for industrial production. Therefore, industrial synthesis forms Cuprous oxide with controllable appearance size is still a research hotspot in this field

Embodiment

[0019] The preparation method of the cuprous oxide nanocrystal cube and the hollow polyhedron involved in the present embodiment is: firstly adopt copper acetate monohydrate (Cu(CH 3 COO) 2 ·H 2 O) and sodium hydroxide (NaOH) react first, then with sodium lauryl sulfate (C 12 h 25 SO 4Na) is a surfactant and a stabilizer, and then deionized water and hydrazine hydrate (N 2 h 4 ·H 2 (2) aqueous solution makes cuprous oxide nanocrystal cube and hollow polyhedron, and its specific technological process comprises the following steps:

[0020] (1) Dissolution: first weigh two portions of 0.87g sodium lauryl sulfate, dissolve them in 89ml and 69mL of deionized water solvent respectively, and stir until they are evenly dissolved;

[0021] (2) Add copper acetate: then add 5ml 0.1mol / L Cu(CH 3 COO) 2 Aqueous solution, stir vigorously until dissolved evenly;

[0022] (3) Add NaOH: Then keep the temperature of the water bath at 34°C, add 2ml of NaOH aqueous solution to the solu...

Abstract

The invention belongs to the technical field of preparation of transition metal oxides and relates to a preparation method of Cu2O nanocrystalline cubes and hollow polyhedrons to be applied to preparation occasions of catalytic materials, antifouling paint, insecticides as well as various copper salts, analytical reagents, red glass, copper plating and copper plating alloy solutions. The problem about industrial preparation of Cu2O nanocrystalline cubes and hollow polyhedrons is solved, and synthesized nanocrystals have good photocatalytic performance, can quickly adsorb azo dyes, are easy toseparate and have a good detection effect on nitrobenzene in a Na2SO4 solution. Firstly, copper acetate monohydrate and sodium hydroxide are subjected to a reaction, sodium dodecyl sulfate is used asa surfactant and a stabilizer, deionized water and a hydrazine hydrate aqueous solution in different volume ratios are added, and the Cu2O nanocrystalline cubes and hollow polyhedrons are prepared. The preparation technology is simple, the principle is reliable, the preparation cost is low, and products are high in purity, good in performance, wide in application range and environmentally friendlyin use.

Description

Technical field: [0001] The invention belongs to the technical field of transition metal oxide preparation, and relates to a method for synthesizing hollow and solid nanocrystals with different shapes by using a water bath method, especially a method for preparing cuprous oxide nanocrystal cubes and hollow polyhedrons, which are used in catalysts , photocatalytic materials, electrocatalytic materials, manufacturing ship bottom antifouling paint, insecticides, and various copper salts, analytical reagents, red glass, and also used in the preparation of copper plating and copper alloy plating solutions. Background technique: [0002] Cuprous oxide is an important new inorganic chemical raw material, widely used in marine antifouling, photoelectric conversion, catalytic degradation, sensors and other fields, because the physical and chemical properties of cuprous oxide depend to a large extent on its crystal size and Therefore, the synthesis of cuprous oxide with controllable m...
