Tungsten Oxide One-dimensional Nano Material and Preparation Method

The present invention aims to provide a one-dimensional tungsten oxide material and preparation method, using a simple hydrothermal preparation, operation is simple, easily available raw materials, low cost, environmentally friendly non-toxic solvent that can a large number of synthesis, preparation of WO3 nanowires superior performance, versatile, suitable for large-scale promotion, with significant economic benefits.

The present invention is one-dimensional material is tungsten oxide tungsten oxide nanowires, a length of several hundred nanometers to several microns, width 5-20 nm.

The present invention is a one-dimensional tungsten oxide material preparation method: distilled water elemental tungsten powder are mixed, stirred in an autoclave, the reactants at the reaction temperature 423-478K 1-30 days, then filtered, 323-373K temperature drying 12-24h obtain said tungsten oxide one-dimensional nanomaterials.

The present invention is a significant advantage: The present invention at lower temperatures and does not add any surface active agents and conditions, the templating agent, a simple hydrothermal method of WO3 nanowires prepared, the operation is simple, readily available raw materials get low cost, environmentally friendly non-toxic solvent, can be a lot synthesis, preparation of WO3 nanowires superior performance, versatility, is a good new energy materials that can be used photoelectrocatalysis, solar cells, sensors, lithium ion batteries and Field emission, etc.; suitable for large-scale promotion, with significant economic benefits.

The present invention is a one-dimensional tungsten oxide material preparation, characterized in that: said one-dimensional nano material is tungsten oxide tungsten oxide nanowires, a length of several hundred nanometers to several microns, width 5-20 nm, preparation process as follows: the distilled water elemental tungsten powder are mixed, stirred in an autoclave, the reactants in the reaction at a temperature 423-478K 1-30 days, then filtered and dried at a temperature 323-373K 12-24h to give the said one-dimensional materials, tungsten oxide, wherein the amount of reactor volume of distilled water for 50 to 75 volume% elemental tungsten powder in an amount of 0. 01 ~ 0. 5g, the amount of distilled water with a weight ratio of 1:50 ~ 1: 3750.
