Abstract

The invention discloses a method for synthesizing cuprous oxide nano-cubes on a large scale based on a continuous kettle type device. The device required by the method comprises a micro-mixer, continuous reaction kettles connected in series and a product collection kettle. The method for synthesizing the cuprous oxide nano-cubes comprises the following steps: (1) preparing a reaction raw materialA which is a mixed solution of copper sulfate, sodium citrate and sodium hydroxide; (2) preparing a reaction raw material B which is an ascorbic acid solution; (3) mixing the raw materials by virtue of the micro-mixer, feeding the mixture into the continuous reaction kettles connected in series for mixing and reacting, and collecting a reaction product by virtue of the product collection kettle; and (4) diluting, centrifuging, separating and washing a collected product solution to obtain the cuprous oxide nano-cubes. The method realizes continuous synthesis of the cuprous oxide nano-cubes, andis good in stability, high in yield and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering and nanometer materials, and in particular relates to a method for synthesizing cuprous oxide nano cubes in large quantities based on a continuous kettle type device. Background technique [0002] Cuprous oxide is a P-type semiconductor material, and many studies on cuprous oxide have been carried out, such as gas sensing, photodegradation, photolysis of water, and lithium-ion batteries. In industrial production, it can be used as coating, bactericide, catalyst, flame retardant material, electrode material, information storage material, etc. It is of considerable practical and economic significance to realize the continuous production of cuprous oxide in industry. [0003] Among the morphology of cuprous oxide, nanocubes represent the most important crystal structure of cuprous oxide, because other concentrated crystal morphology (such as: nanocage, octahedron or more complex structu...
