Synthesis of visible-light absorbing CoFe{sub 2}O{sub 4} sensitized TiO{sub 2} nanotube arrays electrode with enhanced photoelectrochemical performance
Graphical abstract: - Highlights: • TiO{sub 2} nanotube sensitized with CoFe{sub 2}O{sub 4} nanocrystals was synthesized by a facile hydrothermal method. • CoFe{sub 2}O{sub 4} nanocrystals were loaded to the outer and inner surface of TiO{sub 2} nanotube. • The CoFe{sub 2}O{sub 4} sensitized TiO{sub 2} nanotube electrode has a strong photoresponse to the light. - Abstract: TiO{sub 2} nanotube arrays sensitized with CoFe{sub 2}O{sub 4} nanocrystals were successfully synthesized via a facile hydrothermal method. The as-prepared sample was studied by X-ray diffraction (XRD), field emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX) to characterize its phase structure, morphology and chemical composition. Enhanced absorption in both UV and visible-light regions was observed for the CoFe{sub 2}O{sub 4} sensitized TiO{sub 2} nanotube arrays. The photocurrent density of CoFe{sub 2}O{sub 4} sensitized TiO{sub 2} nanotube arrays electrode was 30 times as great as that of bare TiO{sub 2} nanotube arrays electrode.
