Embodiment 1

[0033] This embodiment provides a method for manufacturing a CuO catalyst containing oxygen vacancies, which mainly includes the following steps:

[0034] (1) Preparation of CuO nanosheets

[0035] Step 1: Dissolve 60g of sodium hydroxide (NaOH) and 11g of cetyltrimethylammonium bromide (CTAB) in 450ml of distilled water, pour the mixed solution into a 1000ml round bottom flask, and heat up to 60 °C, recorded as solution A.

[0036] Step 2: take by weighing 1.7g copper nitrate trihydrate (Cu(NO 3 ) 2 ·3H 2 O) Dissolve in 50ml distilled water, record as solution B.

[0037] Step 3: Slowly add solution B to solution A, and keep stirring during the addition process to obtain a blue solid-liquid mixture.

[0038] Step 4: After reacting for 60 minutes, a solid-liquid mixture is obtained. After standing still for a period of time, the supernatant is filtered off, and the precipitate is washed by suction filtration with water and ethanol. A black powder was obtained.

Abstract

The invention discloses a method for producing oxygen vacancy-containing CuO nanosheets. The method comprises the following steps: preparing CuO nanosheets and treating the CuO nanosheets with sodiumborohydride. According to the preparation method, the CuO catalyst containing the oxygen vacancy is prepared by adopting a chemical preparation method at a low temperature, so the cost is relatively low, the synthesis method equipment and process are simple, the operation is simple and convenient, a large amount of catalysts can be synthesized, and the practical production and application are facilitated. For the CuO catalyst containing the oxygen vacancy, through the existence of the oxygen vacancy, the activity of the catalyst is improved, and particularly in a propylene catalytic activity test, T50 is reduced by about 70 DEG C.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for manufacturing CuO nanosheets containing oxygen vacancies. Background technique [0002] In recent years, environmental issues have attracted more and more attention. Hydrocarbons produced by the combustion of automobiles, petrochemicals and power plants pose a serious threat to the atmospheric environment and human health. Among the few technologies for reducing hydrocarbon emissions, such as condensation recovery, adsorption, and fuel-assisted combustion, catalytic oxidation is considered the most effective method. [0003] Noble metal catalysts such as gold (Au), platinum (Pt), palladium (Pt), and 珯 (Rh) are widely used in the catalytic oxidation of harmful gases such as CO and C-H compounds. However, due to the shortage of resources, high cost, high temperature and easy sintering, noble metal catalysts are not conducive to commercial applicati...
