Preparation of fine, uniform nitrogen- and sulfur-modified TiO2 nanoparticles from titania nanotubes
Preparation of fine uniform nitrogen sulfur-modified TiO2 nanoparticles titania nanotubes
2010/11/25
TiO2 nanoparticles modified with nitrogen and sulfur were prepared from titania nanotubes by a facile wet chemistry method. The samples synthesized with different thiourea/TiO2 ratios showed a uniform...
