4.Results and Discussion
Effect of Acid.The kind of acid used in the aqueous
phase had a significant effect on the phase composition
of the TiO2 product.The feedstock was prepared as
follows:3.4 mL of tetrabutyl titanate and 4.0 or 8.0 mL
acid (5.0Mor 10.0Mhydrochloric acid or nitric acid) were
mixed,and this mixture was then added dropwise into
the other mixture of Triton X-100/n-hexanol clohexane.
The concentrations of tetrabutyl titanate and acid were
kept at 0.25Mand in the range of 0.5-2.0 M,respectively.
The hydrothermal reaction was first performed at 120 °C
for 12 h.The XRD patterns of the products prepared in
different acids with different acidity are given in Figure
1,and TEM micrographs of some products are shown in
