Abstract

The invention discloses a method for preparing nanosheet cluster-structure cupric sulfide from a titanium-copper amorphous alloy. The cupric sulfide powder prepared by the method has the advantages of large specific area and high photocatalytic activity. The method comprises the following steps: putting a titanium-copper amorphous alloy strip (comprising 30-70 atm% of Ti and 30-70 atm% of Cu) and a sulfuric acid water solution with the molar concentration of 10-15M into a closed vessel to react at 60-120 DEG C for 24-96 hours, flushing the sample prepared by reaction with deionized water, and drying in a 50-DEG C drying box to obtain the nanosheet cluster cupric sulfide powder. The synthesis method has the advantages of simple manufacturing process and low raw material cost, and is simple, feasible and economical.

Description

technical field [0001] The invention relates to the preparation and application of copper sulfide, in particular to the preparation and application of copper sulfide with a nanosheet cluster structure. Background technique [0002] Micro-nano materials with special morphology have excellent optical, electrical, magnetic and catalytic properties, and have great application prospects in micro-nano devices. Copper sulfide is a wide bandgap semiconductor material with a bandgap width of about 2.0ev. Because of its special physical and chemical properties such as certain catalytic activity and photoluminescence, the copper sulfide has great application potential in the fields of catalysis, solar cells, superconductors, and gas sensors. At present, its synthesis methods are various, such as hydrothermal method, chemical deposition method, sonochemical method and template method. These existing synthesis methods generally require higher reaction temperature, reaction pressure, lo...
