Abstract  

Core-shell photocatalysts of hierarchical porous nanospheres (HP-Fe2O3@TiO2) have been designed and prepared using solvothermal and sol-gel methods. Transmission electron microscopy (TEM) images confirm that the obtained samples a hierarchical porous structure, which results from both the macroporous structure of the core (Fe2O3) and the mesoporous structure of the shell (TiO2). X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and nitrogen adsorption-desorption isotherms were employed to characterize the structure and properties of HP-Fe2O3@TiO2 nanospheres. We investigated the photocatalytic degradation (in the presence of H2O2) of methylene blue (MB) irradiated under visible and ultraviolet light. The observed photocatalytic performance of HP-Fe2O3@TiO2 nanospheres is attributed to the synergetic effects of the core-shell structure, which indicates that the TiO2 shell enhances the photocatalytic performance of α-Fe2O3. HP-Fe2O3@TiO2 (1 mL Ti(OC4H9)4 (TBT)) possesses the highest photodegradation reaction constant among all samples under visible light irradiation. Moreover, HP-Fe2O3@TiO2 (4 mL TBT) has an optimal monodisperse morphology and achieves high photocatalytic activity under ultraviolet light irradiation.
