specific Embodiment

[0017] Example 1. In a 50ml round bottom flask, according to the molar ratio Cu(CH 3 COO) 2 : NaOH:PVP ratio of 1:2:10, add copper acetate aqueous solution, sodium hydroxide triethylene glycol solution, and PVP aqueous solution in turn, keep the total volume at 15ml, mix well to form a homogeneous light blue solution, Then put it in a microwave oven and heat it at 800 watts for 20 seconds while stirring. Stop microwave heating after the color of the solution turns bright dark brown. That is, cubic copper oxide nanoparticles with an average particle diameter of 41 nm were obtained.

[0018] Example two, in a 50ml round bottom flask according to the molar ratio Cu(CH 3 COO) 2 : NaOH:PVP ratio of 1:1:5, add copper acetate aqueous solution, sodium hydroxide triethylene glycol solution, and PVP aqueous solution in turn, keep the total volume at 15ml, mix well to form a homogeneous light blue solution , then put it in the microwave oven, and heat it at 850 watts for 65 seconds ...

Abstract

The invention relates to cubic copper oxide nanoparticles, a preparation method and application thereof. The present invention uses microwaves as the heating medium to mix the copper acetate aqueous solution, the sodium hydroxide triethylene glycol solution and the polyvinylpyrrolidone aqueous solution evenly, stir and microwave-heat the solution until the color of the solution becomes bright dark brown, then stop the microwave heating to obtain Cubic copper oxide nanoparticles. The method of the invention has a simple experimental process and does not require complex and harsh process conditions, and the obtained product can be used to prepare gas sensitive elements.

Description

1. Technical field [0001] The invention relates to cubic copper oxide nanoparticles, a preparation method and application thereof. 2. Background technology [0002] Ordinary copper oxide is a multifunctional fine inorganic material with a wide range of uses, mainly used in the fields of printing and dyeing, glass, ceramics, medicine and catalysis. When the particle size of ordinary copper oxide particles reaches the nanometer level, its function will be more unique and its application will be more extensive. At present, solid phase reaction method, hydrothermal method, alcohol thermal method, precipitation method, spray pyrolysis method, liquid phase precipitation technology with double jet flow control, sonochemical method, pressure-hydrothermal method, microemulsion method and laser steaming are widely used. Method, microwave boiling reflux method, electrochemical method, template method, etc., but there are many problems to be solved. First, the synthesis conditions are...
