Abstract

The invention provides a preparation method of beta-nickel hydroxide nanosheets. The preparation method comprises the following steps: (1) cleaning treatment of a copper bar: the copper bar is washed with acetone, ethanol, 2 mol / L dilute hydrochloric acid and distilled water under ultrasonic conditions; (2) preparation of the beta-nickel hydroxide nanosheets: at room temperature, bivalent nickel salt and alkali are respectively dissolved in distilled water and stirred until the bivalent nickel salt and alkali are dissolved; the bivalent nickel salt solution and the alkali solution with the equal volume amount are weighted and poured into a reaction kettle, the cleaned copper rod is put into the reaction kettle, the reaction kettle is sealed, the mixture is allowed to react at 180 DEG C for 8-12 hours, the copper rod growing with a blue-green substance is washed by distilled water and then naturally dried, so as to obtain the nanosheets. The method is high in reproducibility, simple and convenient to operate, low in synthesis cost and suitable for industrial preparation, the surface of the metal copper is uniformly covered with the nanosheets, the nanosheets have a large specific surface area and can be fully contacted with the object to be detected, and the copper bar with the nanosheets can be used as the electrode to detect hydrazine hydrate and hydrogen peroxide in water.

Description

technical field [0001] The invention relates to a preparation method of β-nickel hydroxide nanosheets. Background technique [0002] In recent years, due to the increasing demand for nanomaterials, the research and development of nanomaterials has developed rapidly, and they are widely used in coatings, traditional materials, electronic equipment, medical equipment and other fields. It is worth mentioning that due to its unique structure and size, composite nanomaterials are different from general macroscopic materials in terms of electrical, mechanical, thermal, optical and magnetic properties, and may also have special properties and properties that the original components do not have. Features. [0003] The oxyhydroxides of transition metals are important mineral materials, which have a large number of applications, especially in catalytic and electrocatalytic reactions. Nano-nickel hydroxide has a small particle size and a large specific surface area, which can increas...
