Embodiment 1

[0020] Embodiment 1: Manganese chloride, sodium vanadate, SDS and water are evenly mixed and put into a reaction vessel and sealed, wherein the mol ratio of manganese chloride and sodium vanadate is 1: 2, manganese chloride, sodium vanadate Accounting for 10% of the weight of the water solvent, SDS accounts for 8% of the weight of the water solvent. Then it was kept at a temperature of 180° C. for 24 hours, and finally a velvety brown product with manganese vanadate nanoneedle structure with a length of about 10 μm and a diameter of the nanoneedle tip of about 50 nm was obtained.

Embodiment 2

[0021] Embodiment 2: Manganese chloride, sodium vanadate, SDS and water are evenly mixed and put into a reaction vessel and sealed, wherein the mol ratio of manganese chloride and sodium vanadate is 1: 2, manganese chloride, sodium vanadate Accounting for 5% of the weight of the water solvent, SDS accounts for 5% of the weight of the water solvent. Then it was kept at a temperature of 180° C. for 24 hours, and finally a velvety brown product with manganese vanadate nanoneedle structure with a length of about 10 μm and a diameter of the nanoneedle tip of about 50 nm was obtained.

Embodiment 3

Abstract

The invention discloses a manganese vanadate nanoneedle structure and a synthesis method thereof, belonging to the technical field of preparation of nano materials. The manganese vanadate nanoneedle structure disclosed by the invention is composed of an MnV2O5 orthorhombic phase which is about 10 mu m long, and the diameter of the nanoneedle tip is about 50 nm. The synthesis method comprises the following steps: by using manganese chloride and sodium vanadate as raw materials, sodium dodecylsulfate (SDS) as a surfactant and water as a solvent, evenly mixing the manganese chloride, sodium vanadate, SDS and water, sealing the mixture in a reaction vessel, and keeping at the temperature of 120-180 DEG C for 6-24 hours, thereby finally obtaining the brown flocculent manganese vanadate nanoneedle structure, wherein the amount of the manganese chloride and sodium vanadate is not greater than 10 wt% of the water, and the amount of the SDS is not greater than 10 wt% of the water. The invention has the advantages of simple synthetic process, and no environmental pollution by the raw materials and synthetic process, conforms to the trend of modern industry requiring environmental protection, and can implement mass synthesis of the manganese vanadate nanoneedle structure.

Description

Technical field: [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a manganese vanadate nano needle structure and a synthesis method thereof.
