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.

AbstractThe present work shows the growth of nordstrandite microcrystals observed by transmission and scanning electron microscopy. Nordstrandite was synthesised from non-crystalline aluminium hydroxide reacted in 20% ethylene glycol/water solution, at room temperature. This material was characterized by TEM, SEM, SAED, XRD and EDS/TEM, during six month and revealed the formation and growth of nordstrandite. Fibrillar pseudoboehmite is the only aluminium hydroxide which could be identified during the first two weeks. The nuclei grow, from complete dissolution/recrystallization of pseudoboehmite fibrils, into platy rectangular microscrystals of nordstrandite. Some tabular microcrystals recrystallise, forming after six months only the multi-point nordstrandite stars. This electron-optical study suggest that the star shape results from the overlapping of rectangular plates, and pseudoboehmite fibrils act as the precursor of nordstrandite crystallisation in ethylene glycol/water solution.
