Abstract

The invention discloses a preparation method of honeycombed CuO nano structure, which includes concrete steps as follows: copper sheet is burnished and soaked in 30% hydrochloric acid for 8 minutes to 10 minutes, and then put into acetone for ultrasonic processing to obtain pure copper sheet which is taken as a positive electrode; graphite is selected as a negative electrode; 3mol / L KOH is adopted as an electrolytic solution; voltage ranges from 3V to 5V; after electrolytic deposition is carried out for 3h to 5h, the copper sheet is taken out and a layer of blue Cu(OH)2 precursor is generated on the surface of the copper sheet; and under the protection of N2, the obtained Cu(OH)2 precursor is heated at 150 DEG C to 160 DEG C for 2.5h to 3.5h and then taken out, and a layer of black honeycombed nano CuO is generated on the surface of the copper sheet. Compared with the nano structure synthesized in the past, the preparation method is prominently characterized by: (1) novel method; (2) novel appearance; (3) simple equipment; (4) simple operation; (5) no requirement of catalysts, resource conservation; and (6) low cost.

Description

technical field

[0001] The invention relates to a nano material, specifically a honeycomb CuO nano material, and a preparation method of the nano material; it belongs to the technical field of semiconductor materials, optoelectronic materials and devices. Background technique

[0002] CuO is a wide bandgap semiconductor with large exciton binding energy. It has great application prospects in optoelectronic devices, photocatalysis and solar cells. Because of its thermal stability, high mechanical strength and chemical stability Such special properties have aroused people's interest in the field emission characteristics of its nanostructures. Especially in recent years, the continuous improvement of video technology has led to the continuous improvement of people's visual experience. The original CRT (cathode ray tube) and its LCD liquid crystal display have highlighted some of their disadvantages. The cost of plasma is too high. People are more and more interested in field e...
