Abstract EN
A core/multi-shell-structured Fe3O4/C/TiO2 magnetic photocatalyst is prepared via vapor phase hydrolysis process.
The as-synthesized core/multi-shell-structured composite is characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high-resolution electron microscopy (HRTEM), N2 adsorption-desorption isotherm analyses, vibrating sample magnetometer (VSM), and ultraviolet-visible (UV-Vis) absorption spectroscopy.
TEM and HRTEM show that well-crystallized anatase TiO2 nanocrystals are immobilized on the surface of as-prepared Fe3O4/C microspheres with dimensions around 200 nm.
N2 adsorption-desorption isotherm analysis shows that the obtained photocatalyst exists disorderedly mesoporous structure.
The photocatalytic efficiency of the catalyst in degradation of methylene blue is evaluated, and the Fe3O4/C/TiO2 photocatalyst with low TiO2 content (37%) has a relatively higher activity than commercial anatase TiO2.
The intermediate carbon layer avoids the photodissolution of Fe3O4 effectively, and the recycling property is largely improved due to the existence of magnetic Fe3O4 core.
