Fe‐doped TiO 2 /0.03SnO 2 hybrid nanofiber has been prepared via electrospinning method. The magnetic property versus Fe‐doping content was characterized, and the corresponding photocatalytic activity under visible light radiation was evaluated by using Rhodamine B (RhB) degradation as a probe reaction. The hybrid nanofiber has proved to be an excellent visible light‐excitable photocatalyst with much higher photocatalytic activity than undoped TiO 2 /SnO 2 hybrid nanofibers. The magnetic properties have also been characterized for the Fe‐TiO 2 /SnO 2 nanofibers before and after annealing under vacuum atmosphere, and nanofibers shows obvious ferromagnetic property at room temperature as they were annealed. It is believed that this nanofiber may become a potential photocatalyst in environmental remediation.
