Embodiment 1

[0021] Embodiment 1: Put germanium oxide, copper acetate, sodium vanadate and water into reaction container after uniform mixing and seal, wherein the mass percent of vanadium in copper germanate is 5%, and the mol ratio of germanium oxide and copper acetate is 1:1, the amount of germanium oxide, copper acetate and sodium vanadate is 10% of the water weight. Then, the temperature was kept at 180° C. for 24 hours, and light blue flocculent vanadium-doped copper germanate nanowires were finally obtained.

Embodiment 2

[0022] Embodiment 2: Put germanium oxide, copper acetate, vanadium chloride and water into the reaction vessel after uniform mixing and seal, wherein the mass percent of vanadium in copper germanate is 3%, and the mol ratio of germanium oxide and copper acetate is 1:1, the amount of germanium oxide, copper acetate and vanadium chloride is 5% of the water weight. Then, the temperature was kept at 180° C. for 12 hours, and light blue flocculent vanadium-doped copper germanate nanowires were finally obtained.

Embodiment 3

[0023] Embodiment 3: Put germanium oxide, strontium acetate, sodium vanadate and water into the reaction vessel after uniform mixing and seal, wherein the mass percentage of vanadium in strontium germanate is 2%, and the molar ratio of germanium oxide and strontium acetate is 1:1, the amount of germanium oxide, strontium acetate and sodium vanadate is 15% of the water weight. Then, the temperature was kept at 180° C. for 6 hours, and white flocculent vanadium-doped strontium germanate nanowires were finally obtained.

Abstract

The invention discloses a preparation method of a vanadium doped germanate nanowire and belongs to the technical field of functional materials. The method comprises the following steps: evenly mixing germanium oxide, an acetic acid salt, a vanadium compound with water by taking sodium vanadate, ammonium metavanadate, sodium metavanadate, potassium metavanadate, vanadium oxide or vanadium chloride as a doping source, the germanium oxide and the acetic acid salt as raw materials and the water as a solvent; putting in a reaction container and sealing; and performing heat preservation for 0.5 to 24 hours at 120 DEG C to 180 DEG C, thus obtaining the floccus vanadium doped germanate nanowire. The vanadium doped germanate nanowire has the good visible light photocatalysis property, and has a good application prospect in the fields of industrial wastewater treatment, environment-friendly self-cleaning coatings and self-cleaning glass.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a vanadium-doped germanate nanowire and a preparation method thereof. Background technique [0002] Germanate nanowires have good electrochemical, optical, photocatalytic and electrical properties, and have good application prospects in electrochemical sensors, photocatalysis, optical and nanoelectronic devices, and have aroused people's research interest. At present, various germanate nanowires have been reported, such as strontium germanate nanowires, copper germanate nanowires, calcium germanate nanowires and manganese germanate nanowires. These germanate nanowires have good semiconductor photocatalytic properties, can absorb ultraviolet light, and can effectively degrade organic dye pollutants such as methylene blue and methyl orange. They are expected to be used as photocatalysts in industrial wastewater treatment and self-cleaning materials to reali...
