Hydrothermal Reduction

Highly dispersed TiO2 nanotubes (TiO2-NTs) were synthesized via the reaction of anatase TiO2 powder with NaOH solution. Au nanoparticles of about 5 nm were deposited on the surface of TiO2-NTs with hydrothermal reduction method. The prepared nanocomposites were well characterized with TEM and XRD. Their photocatalytic properties and reducing ability were investigated by UV-Vis absorption and photocatalytic reduction of Cd2+ ions with different amount of TiO2-NTs and TiO2-NTs (Au) varying from 0.1g to 0.001g. The results from absorption patterns and AAS showed that the absorption intensity of TiO2-NTs (Au) was higher compared with that of TiO2-NTs. Moreover, the concentration of remanent Cd2+ (0.48mg/L) using TiO2-NTs (Au) was lower than that of Cd2+ (0.65mg/L) using TiO2-NTs.
