Abstract

The invention relates to a Sn1‑0.5xCuxS2 nano flower and its preparation and application; it belongs to the technical field of design and preparation of special nano materials. The chemical formula of the nanoflowers of the present invention is Sn1-0.5xCuxS2, wherein the value of x is 0.01-0.25. The nanoflowers are composed of Sn1‑0.5xCuxS2 nanosheets through mutual mosaic or interpenetration. Its diameter is 1-5μm, and its specific surface area is 63-83㎡ / g. The preparation method is as follows: after dispensing Sn source, Cu source and S source according to the designed composition, add the prepared Sn source, Cu source and S source into the solvent and mix evenly to obtain a mixed solution, and then place the mixed solution in the reaction React in a kettle at 160-200°C to obtain Sn1-0.5xCuxS2 nanoflowers. The Sn1‑0.5xCuxS2 nanoflowers designed in the present invention can be used to catalyze the decomposition of organic matter. The invention has reasonable component design, simple preparation process, excellent and stable performance of the obtained product, and is convenient for large-scale industrial application.

Description

technical field [0001] The present invention relates to a kind of Sn 1-0.5x Cu x S 2 Nanoflowers and their preparation and application; belong to the technical field of design and preparation of special nanomaterials. Background technique [0002] With the rapid economic growth, energy shortage and environmental pollution have become two major problems plaguing mankind. If the energy shortage is not solved, the development and progress of human beings will be hindered; if the environmental pollution is not solved, the survival of human beings will be in jeopardy. Therefore, countries around the world have invested huge manpower and material resources in the hope of changing this predicament. Solar energy is one of the energy sources with abundant reserves. Semiconductor photocatalytic materials can convert solar energy into chemical energy and degrade organic or heavy metal pollutants. Semiconductor photocatalytic materials have been extensively studied. [0003] In ter...
