Embodiment 1

[0013] Add 0.11 g of ammonium metavanadate, 0.05 g of cupric chloride, and 0.1 g of sodium hydroxide into 35 ml of distilled water, ultrasonically oscillate for 15 minutes at room temperature, stir for 3 hours, and put the mixed liquid into a 50 ml polytetrafluoroethylene-lined In the stainless steel water heating tank, after tightening the lid, put the water heating tank in an oven at 170°C and keep it warm for 1 hour; increase the temperature of the oven to 200°C, keep it warm for 8 hours, take the water heating tank out of the oven, and place it in the air to cool to room temperature, then open the hydrothermal jar, pour out the mixture inside, and centrifuge in a centrifuge at 4000 rpm to obtain a precipitate, which is then repeatedly washed with water and ethanol to obtain a CuO material.

Embodiment 2

[0015] Add 0.2 g of ammonium metavanadate, 0.5 g of copper acetate, and 0.5 g of potassium hydroxide into 35 ml of distilled water, ultrasonically oscillate for 15 minutes at room temperature, stir for 3 hours, and put the mixed liquid into 50 ml of polytetrafluoroethylene-lined stainless steel In the water heating tank, after tightening the lid, put the water heating tank in an oven at 150°C and keep it warm for 3 hours; raise the temperature of the oven to 220°C and keep it warm for 4 hours, then take the water heating tank out of the oven and place it in the air to cool to At room temperature, pour out the precipitate inside, centrifuge in a centrifuge at 4000 rpm, and then wash the precipitate repeatedly with water and ethanol to obtain CuO material.

Abstract

The invention belongs to the technical field of inorganic materials preparation, and particularly relates to a preparation method of copper oxide (CuO) powder. CuO has a broad application prospect in the fields of removal, photocatalysis, magnetic storage mediums and the like of gas sensors, biosensors, nano fluids, light detector, energetic materials, field emission, super capacitors and inorganic pollutants. According to the invention, CuO is prepared by using a method for the hydrothermal pyrolysis of copper vanadate, copper vanadate is prepared firstly, and then the copper vanadate as a raw material is pyorlyzed into CuO. Compared with existing CuO preparation methods, by using the new method, the morphology and structure of CuO are easily controlled, and particularly, an orientationally arranged growth mechanism in CuO crystals can be regulated, so that porous-structured and solid-structured CuO mesocrystals are prepared.

Description

technical field [0001] The invention belongs to the technical field of inorganic material preparation, and in particular relates to a method for preparing copper oxide powder. Background technique [0002] Copper oxide (CuO) has been a transition metal oxide that has been a research hotspot, and it is a p-type semiconductor with a narrow band gap (1.2eV). CuO is a valuable solar cell material with high solar absorption capacity, low thermal emission, relatively good electrical properties and high carrier concentration. CuO is an effective catalyst for the oxidation of CO and NO, as well as the oxidation of volatile organic gases such as methanol. The superhydrophobicity of nano-CuO can be used as a self-cleaning material with lotus leaf effect, and can also be used for surface protection, textile, water / oil separation, etc. In addition, CuO is not as an anode material for lithium batteries as SnO 2 and TiO 2 That has received a lot of attention. However, CuO nanostructur...
