Photocatalytic Degradation of Organics Diluted in Water Using TiO_2 Loaded on Fluoride-Modified Mesoporous Silica

摘要

The synthesis of the hydrophobic mesoporous silica MS(F) was performed using tetraethyl orthosilicate, triethoxyfluorosilane as the source of the fluoride and dodecylamine as templates. The TiO_2 loaded on the hydrophobic MS(F) (TiO_2/MS(F)) exhibited the efficient photocatalytic performance for the degradation of alcohols (iso-butanol) diluted in water. The photocatalytic reactivity for the degradation increased with increasing the content of fluoride ions on these photocatalysts. The hydrophobic mesoporous surface is suitable as the photocatalytic reaction field for the degradation of organic compounds diluted water.
