内容記述タイプ Abstract
内容記述 A water-floatable TiO2 photocatalyst support was successfully produced from organosilica via sol-gel reactions of organosilanes (octyl- and methyl-silyl trichlorides and 3-aminopropyltrimethoxysilane). 3-Aminopropyltrimethoxysilane in silane coupling agents was shown to have an important role in depositing highly dispersed TiO2 nanocrystals onto organosilica particles. Calcination of the as-made sample at 400 degrees C in an airflow resulted in the loss of octyl- and 3-aminopropyl groups, modifying polymethylsiloxane while maintaining water floatability. Calcination led to an increase in the specific surface area from 88 to 230 m(2)/g and the growth of anatase crystallites. Floatability was not observed when the as-made sample was calcined at 600 degrees C, showing that methyl groups acted as surfactants at the air-water interface. Formic acid in water was catalytically oxidized over the water-floatable sample upon irradiation by a solar simulator. The evolved CO2 became saturated when the surface of the aqueous solution was filled with the floating particles. We demonstrated the importance of the floating photocatalyst with respect to the efficiency of light receipt and facile recovery from liquid media. (C) 2016 Elsevier B.V. All rights reserved.
