Abstract

The invention belongs to the nano-material technical field, and relates to a preparing method for molybdenum oxide - polyaniline composite nanowire and nanotube. Molybdena - aniline hybrid nano wire precursor is obtained by using molybdate as the source of molybdenum and interacting with aniline,,and the molybdenum oxide - polyaniline composite nanowire and nanotube are obtained by respectively adjusting system pH value under the initiation of oxidizing agent. The nanowire and the nanotube prepared by the method of the invention have the characteristics of a composite construction of nanometer scale, controllable physical and chemical features, large specific surface area, uniform one-dimensional morphology and controllable thickness and length. The prepared composite molybdenum oxide - polyaniline composite nanowire and nanotube have important application value in many fields such as designing of advanced catalyst, electrocatalysis, electrochemical super capacitor, electrode material, sensor, thermoelectric material, the synthesis and application of advanced optics, electrical material and magnetism material.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a method for preparing molybdenum oxide-polyaniline composite nanowires and nanotubes. Background technique [0002] Research on the compounding of inorganic materials and high molecular conductive polymers at the nanoscale has attracted increasing attention. Studies have shown that the compounding of the two can combine their excellent physical and chemical properties and improve each other, making the properties of the compound easier to control and adjust. The prior art discloses that polyaniline has good surface stability, thermal stability and conductivity, and it is widely used in electrochemical capacitors, batteries, sensors and corrosion inhibitors. Molybdenum oxide has unique electrochemical properties and electrocatalytic properties. Combining molybdenum oxide and polyaniline materials at the nanoscale through organic-inorganic compounding will...
