Abstract

The invention relates to the technical field of basic cupric carbonate micro-powder preparation and especially relates to a sheet-shaped self-assembled basic cupric carbonate flower-type ball and a simple preparation method thereof. The sheet-shaped self-assembled basic cupric carbonate flower-type ball is prepared from basic cupric carbonate nanosheets through assembling, the diameter of the flower-type ball is 1 to 10 microns, and the particle shapes of the flower-type balls are uniform. The preparation method comprises carrying out ultrasonic mixing on an aqueous solution of a soluble copper salt and an absolute ethanol-water solution of L-aspartic acid, putting the mixture in a constant-temperature blast oven, carrying out a reaction process and then treating the product to obtain a basic cupric carbonate flower-type ball powder material. The L-aspartic acid, the soluble copper salt, the anhydrous ethanol and the deionized water are mixed under ultrasonic agitation and undergo a hydrothermal reaction to produce the sheet-shaped self-assembled basic cupric carbonate flower-type ball. A series of characteristics show that the sheet-shaped self-assembled basic cupric carbonate flower-type ball produced through a system using L-aspartic acid as a template and a raw material has narrow particle size distribution, uniform distribution of morphology and controllability.

Description

technical field [0001] The invention relates to the technical field of basic copper carbonate micron powder preparation, in particular to a sheet-like self-assembled basic copper carbonate flower ball and a simple preparation method thereof. Background technique [0002] Cu 2 O has the advantages of good stability, easy preparation, non-toxicity, no pollution, and low cost, and is a functional material with broad application prospects. Since the high-intensity photon excitation beam can pass through the Cu 2 O solid, initiates Cu 2 The mutual propagation between O excitons, so it can be applied to the assembly of microdevices such as solar cells, biosensors, lithium-ion batteries, and magnetic storage devices. In addition, Cu 2 The good photoelectric properties of O can also be used as a visible light catalyst to degrade organic pollutants and electrolyze water to generate oxygen under visible light radiation. [0003] Basic copper carbonate as a precursor to prepare Cu...
