Nb2O5 one-dimensional nano material and preparation thereof

Abstract

The invention provides Nb2O5 one-dimensional nanometer material and a preparation method thereof. The Nb2O5 one-dimensional nanometer material relates to a nanometer rod which has the length of hundreds of nanometers to scores of micrometers and the diameter of scores of nanometers to hundreds of nanometers. The preparation method comprises the following steps: mixing simple niobium powder with distilled water, carrying out intensive stirring in an autoclave, carrying out the reaction of reactants at 423 to 478K for 3 to 30 days, then carrying out filtration, and obtaining the final product after drying the product at 323 to 373K for 12 to 24h. The invention adopts a simple hydrothermal method to prepare the product, and has a simple operation process, easily obtained raw material, low cost, and innocuous harmless and environmentally friendly solvent. The Nb2O5 one-dimensional nanometer rod can be synthesized on a large scale and has excellent performance and wide application. The Nb2O5 one-dimensional nanometer rod is suitable for large-scale popularization and has remarkable economic benefits.
