Embodiment 1

[0024] 1) Put 60mL of glycerol and n-dibutyl adipate mixture (volume ratio 2::1) into a three-necked flask, add 2.50g of copper formate solid powder, and add cetyltrimethylammonium bromide at the same time (CTMAB) 0.500 g, the mixture was made into a suspension under constant stirring.

[0025] 2) Slowly increase the temperature of the reaction mixture during rapid stirring. When the temperature rises to 390K, control the temperature to no longer rise, continue to stir and react at 390K for 80 minutes, and naturally cool to room temperature to obtain nano-cuprous oxide of the suspension.

[0026] 3) Dilute the suspension obtained in step 2) with 60 mL of absolute ethanol or acetone, filter under reduced pressure, and then wash with an appropriate amount of absolute ethanol or acetone for 4 times

[0027] 4) Put the cleaned cuprous oxide powder into a vacuum drying oven, and vacuum-dry at 350K for 480 minutes to obtain red nano-cuprous oxide powder microcrystals.

Abstract

The invention discloses a method for preparing nanometer cuprous oxide in a glycerol and dibutyl-adipate mixed liquid system. The method includes the steps that glycerol and dibutyl-adipate mixed liquid serves as reaction system liquid, glycerol serves as a reducing agent, copper formate serves as a copper source, cetyl trimethyl ammonium bromide, sodium dodecyl benzene sulfonate, polyvinyl pyrrolidone and lauryl sodium sulfate serve as a dispersing agent, and nanometer cuprous oxide micro-grains which are of cubic structures are successfully prepared with the solvothermal method. The required raw materials for preparing are low in cost, easy to obtain, simple in technology, convenient to operate, good in repeatability and free of waste liquid discharging, the environment-friendly preparing requirements of a product are met, and the characteristics are quite beneficial to industrial scale production. The nanometer cuprous oxide material has the wide applications in the aspects such as photocatalyst materials, chemical raw materials, photoelectron conversion materials, negative electrode materials and ballast materials of a lithium ion battery and antibacterial materials, and has broad market prospects and the potential value.

Description

technical field [0001] The invention relates to a method for preparing nano cuprous oxide. Background technique [0002] Cuprous oxide is a widely used electronic component material and chemical raw material. It can be used as a fungicide in agricultural production, a colorant in glass industry, a catalyst in organic chemical industry, and a catalyst for the decomposition of organic matter in industrial wastewater. Because the band gap of cuprous oxide is 2.2eV, it is an important semiconductor material, which can be used as photoelectric conversion material, negative electrode material and ballast material of lithium ion battery, etc. Therefore, the preparation of Cu2O particles with specific particle size and shape has a broader market prospect and potential value. [0003] Common preparation techniques for cuprous oxide include electrolysis, solid-phase and liquid-phase methods (sodium sulfite reduction CuSO4 method, hydrazine hydrate reduction method, hydrothermal metho...
