FIG. 1.

(Color online) FE-SEM micrographs of (a), (b) the pure Fe3O4 submicron particles and (d), (e) the Fe3O4@TiO2 submicron particles. Histogram for the particle size distribution of (c) the pure Fe3O4 submicron particles and (f) the Fe3O4@TiO2 submicron particles.

FIG. 2.

(Color online) (a), (b) HR-TEM micrographs of the Fe3O4@TiO2 submicron particles. (c) EDX spectrum data of the Fe3O4@TiO2 submicron particles.

FIG. 3.

(Color online) Room-temperature magnetic hysteresis loops of the pure Fe3O4 submicron particles and the Fe3O4@TiO2 submicron particles.

Image of FIG. 4.
FIG. 4.

(Color online) Absorption spectral change of 2,4,6-TCP in aqueous solution of pH 10 depending on the photocatalytic reaction time with the Fe3O4@TiO2 submicron particles. The UV light from a Xe lamp is utilized for all measurements. Inset represents the ratio between the reaction O.D. (C) and the initial O.D. (Co) of 2,4,6-TCP as a function of irradiation time. In the inset, (a) 2,4,6-TCP only with the light, (b) 2,4,6-TCP with the Fe3O4@TiO2 submicron particles without the light, (c) 2,4,6-TCP with the Fe3O4@TiO2 submicron particles in the light condition.

Image of FIG. 5.
FIG. 5.

Recycling experiment for 2,4,6-TCP photodegradation in the presence of the Fe3O4@TiO2 submicron particles under UV light irradiation. C/Co represents the ratio between the reaction O.D. (C) and the initial O.D. (Co) of 2,4,6-TCP as a function of irradiation time.
