METHOD FOR PREPARING BISMUTH OXIDE NANO-PARTICLE/TITANIA NANO-TUBE ARRAY

摘要

Disclosed is a method for preparing a bismuth oxide nano-particle/titania nano-tube array, which method comprises the following steps: S1. pre-treating a titanium sheet; S2. preparing a TiO₂ nano-tube array by an anodic oxidation method; and S3. self-assembling to prepare the bismuth oxide nano-particle/titania nano-tube array. A complex of the bismuth oxide nano-particle and the titania nano-tube is prepared from the bismuth oxide nano-particle/titania nano-tube array of the present invention by self-assembly and calcination techniques, which solves problems of a complex manufacturing procedure, long time consumption, poor stability and the like in the existing processes.
