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
