Method for preparing Nano tube of zirconium dioxide

Abstract

This invention relates to a method for preparing ZrO2 nanotubes by anodic oxidation. The method comprises: mixing formamide and alcohol solvent at a volume ratio of (1-3):1 to obtain a mixed solvent, preparing 0.5-1.5 wt.% fluoride solution, introducing the fluoride solution into a reactor with Zr plate as the anode and Pt plate or graphite plate as the cathode, performing anodic oxidation under 10-90 V DC at room temperature to generate ZrO2 nanotubes on the Zr plate, falling off during the reaction, separating precipitated to the bottom of the reactor, washing with water, and drying at 105 deg.C to obtain ZrO2 nanotubes. The distance between the anode and the cathode is 1.5 cm. The method has such advantages as simple process, low cost, no pollution and uniform wall thickness of ZrO2 nanotubes.

Description

technical field

[0001] The technical solution of the present invention belongs to oxides of zirconium, in particular, relates to a preparation method of zirconium dioxide nanotubes. Background technique

[0002] Zirconia is the only metal oxide that is simultaneously acidic, basic, oxidizing, and reducing. It is a P-type semiconductor, easy to generate oxygen holes, and has very important scientific research value and application prospects in the fields of catalysts, catalyst carriers, and sensitive materials.

[0003] The performance of zirconia is inseparable from its specific surface area and aggregation state. Due to the large specific surface area and specific structure of zirconia nanotubes, it has great application prospects in heterogeneous catalysis, adsorption, separation, and chemical sensors. In addition, zirconia nanotubes can be used as nanoreactors to synthesize nanocomposite structural materials with excellent optical, electrical, magnetic and catalytic pro...
