Embodiment 1

[0040] A preparation process for α-molybdenum oxide nanowires for industrial production, comprising:

[0041] Step S1, slowly adding 4 parts of high-purity molybdenum powder to 30 parts of H 2 o 2 And 68 parts of pure water in the mixed liquid, filled with O 2 In the sealed reaction kettle as a protective atmosphere, turn on the condensation circulation device, keep the temperature of the reaction kettle at 25°C, and stir thoroughly for 3 hours to form an orange precursor solution;

[0042] Step S2, adjust the concentration of the orange precursor solution to 0.5 mol / L, raise the temperature of the reaction kettle to ensure that the precursor solution is at 180°C, the precursor solution is in a supersaturated state, heat treatment for 48 hours, after the reaction Get Milky MoO 3 nanowire dispersion;

[0043] Step S3, after high-speed centrifugation, washing and drying to obtain a pure α-molybdenum oxide nanowire sample.

[0044] Wherein, the outer shell of the reaction ke...

Embodiment 2

[0055] The difference between this embodiment and Example 1 is that step S1: slowly add 4 parts of high-purity molybdenum powder to 40 parts of H 2 o 2 and 58 parts of purified water in the mixed liquid. All the other steps are the same as in Example 1.

Embodiment 3

[0057] The difference between this example and Example 1 lies in step S1: the temperature of the reactor is 75°C. All the other steps are the same as in Example 1.

Abstract

The invention discloses a preparation process of an alpha-molybdenum oxide nanowire for industrial production, belonging to the field of non-ferrous metal processing. The method comprises the following steps: adding a certain amount of high-purity molybdenum powder into a certain volume of a H2O2 solvent, fully stirring for oxidizing the high-purity molybdenum powder by the H2O2 to prepare an orange precursor solution, heating the orange precursor solution at 180 DEG C for 48h to obtain a milky MoO3 nanowire dispersion, and finally centrifuging at high speed, washing and drying to obtain a high-purity alpha-molybdenum oxide nanowire sample. The crystal growth rate of the MoO3 precursor solution is accelerated by introducing of a matrix plate. The invention provides a method for growing thenano-scale and linear alpha-molybdenum oxide nanowire.

Description

technical field [0001] The invention belongs to the field of nonferrous metal processing, in particular to a preparation process for α-molybdenum oxide nanowires for industrial production. Background technique [0002] In recent years, many research topics have controlled the morphology of molybdenum oxide and tapped the properties of nano-molybdenum oxide to increase the potential application of molybdenum oxide. α-Molybdenum oxide nanowires are a semiconductor material, and the linear morphology has a large specific surface area and can be widely used in Electrode materials for rechargeable batteries, electrode materials for supercapacitors, thermoelectric materials, and electrochromism. [0003] So far, molybdenum-based feedstocks have been widely used in the petrochemical industry as selective oxidation and cracking of hydrocarbons. The morphology of nanomaterials is the key parameter to determine its application. One-dimensional nanomaterials with large specific surfac...
