Developing highly performance TiO2-based photocatalyst for pollutant removal from environmental media is of increasing interest from both research and practical perspectives. However, there are currently few developed materials effective for fully addressing all limitations in the catalytic performance and real application. Herein, we report the fabrication of triple-functional {001}-N-TiO2/VSCF/Fe3O4 through a one-step hydrothermal-template synthesis coupled with composite methods as an effective material towards resolving most of the dilemmas. The resultant composite incorporated efficient pollutant capture and photocatalytic degradation, material recovery into one individual, which consists of a hollow-spherical {001}-N-TiO2 photocatalytic site, a vine-shaped carbon fiber adsorptive loader and a Fe3O4 magnetic-responsive part. When exposed to the pollutant under light irradiation, the {001}-N-TiO2/VSCF composite showed remarkable photocatalytic performance. The magnetic-responsive property of {001}-N-TiO2/VSCF/Fe3O4 facilitated catalyst recovery, the composite exhibited good catalytic stability during recycling uses. Our triple composite {001}-N-TiO2/VSCF/Fe3O4 may be applied as a comprehensive functional, efficient and recyclable material for eliminating the current problems in environmental remediation and purification.
