| Abstract |
With a growing demand for clean and comfortable environment, purification technologies with high efficiency and low cost to reduce the pollutant contents of wastewater are urgently needed. TiO2 is considered to be one of the suitable material for photocatalysts due to its nontoxicity, biological inertness, chemical stability and low-cost. In addition magnetic Fe3O4 particles have been introduced to functionalize core–shell particles due to their unique separable feature that makes it possible to realize convenient recycling of novel metals. In this study, a facile and efficient approach for fabricating Ag-coated Fe3O4@TiO2 particles with a good core-shell structure is demonstrated. The Ag-coated Fe3O4@TiO2 photocatalyst exhibited high photocatalytic activity in the degradation of Rhodamine B (Rh.B) under solar light. Finally, the photodynamic process of Ag-coated Fe3O4@TiO2 rapidly generates reactive oxygen species (ROS). Therefore, the detection methods and generation mechanisms of the intrinsic reactive oxygen species (ROS), as for instance superoxide anion radical (•O2-), hydrogen peroxide (H2O2), singlet oxygen (1O2), and hydroxyl radical (•OH) in photocatalysis, were comprehensively surveyed.
