Abstract

Control of pore size on mesoporous titanium hydroxide denoted as TiO_X(OH)_2+δ with zirconium additive was studied by using different size template molecules. The mesopore diameter of TiO_X(OH)_2+δ increased monotonically with increasing size of the organic template molecule used. The use of a mixture of template molecules with different size allowed for accurate pore size control of TiO_X(OH)_2+δ. Moreover, a pore size between those of single template molecules was obtained using a mixture of two different template molecules. The fluoride ion exchange capacity of Zr-added TiO_X(OH)_2+δ also increased with increasing mesopore diameter, and the largest fluoride ion exchange capacity was achieved on the sample with 3.34 nm pore size, and the fluoride ion exchange capacity was further improved by the accurate control of pore size. The amount of fluoride ions adsorbed was 1.1 mmol/g against 50 ppm NaF solution; this was observed in TiO_X(OH)_2+δ with 4.2 nm pore size, which was obtained using a 3:1 mixture of C₁₂H₂₅NH₂:C₁₄H₂₉NH₂ as the template molecule.
