Fabrication of Titania Tubules with High Surface Area and Well-Developed Mesostructural Walls by Surfactant-Mediated Templating Method
Chem. Mater. 2003, 15, 2011-2016,-0001,():
Titania microtubules with high specific surface areas and well-developed framework mesopores forming the tubular walls by a surfactant-mediated template in the sol-gel process were fabricated in a laurylamine hydrochloride (LAHC)/tetra-n-butyl-orthotitanate (TBOT) system. The outer diameter and the wall thickness of titania microtubules are 2-8 and 0.2-2μm, respectively. The walls of the microtubules consisted of nanochannels with exceptionally uniform pore size. This technique is a convenient and facile procedure for fabricating hierarchical ordered hollow tubules. The possible mechanism of the formation of the microtubules in the present system was discussed in detail.
