Abstract

The invention discloses a preparation method of a regulable basic cupric carbonate micro-nano hierarchical structure. The preparation method comprises the following steps: under the action of magnetic stirring, dissolving a copper source in deionized water to form a blue and transparent solution A; under the action of magnetic stirring, dissolving carbonate in deionized water to form a clear, transparent and colorless solution B; under the action of magnetic stirring, quickly pouring the solution B into the A solution, and continuously stirring for 10 min to form a mixed solution C; sealing the C solution in a container, carrying out standing to obtain a sediment product, and washing with deionized water and absolute ethyl alcohol to obtain green solid powder; drying in a vacuum drying oven till the powder reaches constant weight to obtain the regulable basic cupric carbonate micro-nano hierarchical structure. According to the preparation method, Cu2(OH)2CO3 materials with micro-nano structures of different morphologies are prepared through changing different copper sources to quickly mix with salt containing CO3<2-> ions, and accurate control is achieved according to the situations whether acetate ions are added or heating is adopted; the preparation method is simple, environment-friendly and low in energy consumption; the structure surface is free of any small organic molecule, and the structure is convenient to recycle.

Description

technical field [0001] The invention relates to a preparation method of an inorganic functional micro-nano structure material, in particular to an adjustable basic copper carbonate (Cu 2 (OH) 2 CO 3 ) A method for preparing a micro-nano hierarchical structure. Background technique [0002] Basic copper carbonate (Cu 2 (OH) 2 CO 3 ) has a wide range of applications in organic catalysts, pyrotechnics manufacturing, pigments, electroplating, anti-corrosion, phosphor activation and seed fungicides. Existing Cu 2 (OH) 2 CO 3 The preparation method and process are cumbersome, and the prepared Cu 2 (OH) 2 CO 3 The structure cannot be adjusted, and the prepared material cannot have the characteristics of both nanostructure and microstructure at the same time, which cannot meet market demand. Therefore, a simple, green, low energy consumption and controllable preparation process is sought to meet the requirements of Cu 2 (OH) 2 CO 3 The demand in its application field ...
