Elaboration and photocatalytic properties of CoFe2O4/TiO2 composite nanowires with the side-by-side structure

The one-dimensional composite nanowires of CoFe2O4/TiO2 (CFO/TO) were prepared by the dual needle electrostatic spinning followed by heat treatment. One-dimensional side-by-side nanowire structure is obtained under 500 degrees C and 700 degrees C, which is assembled with numerous nanoparticles of CoFe2O4 and TiO2 along the axis of the nanowire. With the increase of annealing temperature, the side-by-side structure is broken. By contrast, the side-by-side nanowires show the better photocatalytic efficiency. In addition, all samples exhibit ferromagnetic properties which is helpful for recycling. As a result, this work supply a feasible way to fabricate new structure of nanocomposites with better photocatalytic properties.

Automated summary

CoFe2O4/TiO2 (CFO/TO) composite nanowires were prepared by dual needle electrostatic spinning and heat treatment, exhibiting a one-dimensional side-by-side structure with nanoparticles of CoFe2O4 and TiO2 along the axis. As the annealing temperature increases, the side-by-side structure is disrupted, but shows better photocatalytic efficiency.
