Photocatalytic activity of TiO2 nanotubes doped with Ag nanoparticles.

06:57 EDT 20th April 2014 | BioPortfolio

Summary of "Photocatalytic activity of TiO2 nanotubes doped with Ag nanoparticles."

TiO2 nanotubes formed on the surface of commercially pure titanium were prepared by anodizing processing and were then heat-treated. The silver doping was processed with different molar concentration of AgNO3 aqueous solution. The silver-doped TiO2 nanotubes were characterized using field emission scanning electron microscopy, ultraviolet visible near-infrared spectrophotometer and ampere-volts (I-V) curve system. The 20-100 nm Ag nanoparticles were well doped atop, inside, and between the nanotubes. The I-V curve of the TiO2 nanotubes increased with heat treatment temperature. The silver-doped TiO2 nanotubes with anatase plus rutile phases had better photocatalytic activity.
