Preparation of lanthanide series rare-earth doped bismuth titanate nano-tube

Abstract

Disclosed is a method for the production of a lanthanide rare-earth doping bismuth titanate nano-tube, which relates to a method for the production of a bismuth titanate nano-tube. The method solves the problems of complex technique and equipment, long preparation cycle, high cost, low yield and being unable to control the size of the nanostructure material accurately when preparing the lanthanide rare-earth doping bismuth titanate nanostructure material by the prior art. The method of preparation has steps of: firstly, weighting nitrate and tetrabutyl titanate in bismuth salt and lanthanide rare-earth; secondly, preparing a lanthanide rare-earth doping bismuth titanate sol, thirdly, dripping the lanthanide rare-earth doping bismuth titanate sol on the surface of an aluminum oxide template and drying the template after being soaked; fourthly, repeating the third step and preserving the heat of the dried template at a certain temperature; and fifthly, repeating the third and the fourth steps and taking out the template at a certain temperature and then placing the template in a KOH or NaOH solution, thereby obtaining the lanthanide rare-earth doping bismuth titanate nano-tube. The method of preparation has advantages of simple process and equipment, short preparation cycle, low cost, high yield and being able to control the size of the nano-tube accurately.
