Abstract

The invention relates to a preparation method of a novel metal oxide semiconductor nano-material. The preparation method comprises the following steps: supplying power for two metal electrodes placed in water through a pulse direct-current source for generating plasma discharge between the two electrodes, carrying out continuous sputtering attack of the surfaces of the metal electrodes through high-energy plasma generated through discharge, allowing metal atoms or metal atom clusters formed on the surfaces of the electrodes to enter water, and carrying out in-situ oxidation and adhesion to form the metal oxide nano-material having a unique morphology. The method which is operated in a normal-temperature normal-pressure open system has the advantages of simple experiment equipment requirements, strong maneuverability and high product purity.

Description

technical field [0001] The invention belongs to the field of inorganic nanometer materials, in particular to a preparation method of copper oxide and zinc oxide semiconductor nanomaterials. Background technique [0002] The physical and chemical properties of nanoscale metal oxide semiconductors are very different from those of bulk materials, so the research on metal oxide semiconductor nanomaterials has received great attention. [0003] Copper oxide (CuO) and zinc oxide (ZnO) are two important semiconducting materials, which have applications in the fields of catalysts, gas-phase and biosensors, nanostructured varistors, UV absorbers, dye-sensitized solar cells, light-emitting diodes, hydrogen storage, etc. Wide range of applications. In the research and application, it is found that after entering the nanoscale, the particle size and morphology have a great influence on the physical and chemical properties of semiconductor compounds and their application directions. The...
