Structural and photovoltaic properties of highly ordered ZnFe2O4 nanotube arrays fabricated by a facile sol-gel template method
Highly ordered ZnFe2O4 nanotube arrays were successfully prepared using porous anodic aluminum oxide (AAO) template from sol-gel solution. The ZnFe2O4 nanotubes are orderly arranged in parallel and each nanotube is composed of many agglutinating nanoparticles. The UV-vis absorption and surface photo...

| description | Highly ordered ZnFe2O4 nanotube arrays were successfully prepared using porous anodic aluminum oxide (AAO) template from sol-gel solution. The ZnFe2O4 nanotubes are orderly arranged in parallel and each nanotube is composed of many agglutinating nanoparticles. The UV-vis absorption and surface photovoltage spectra of the ZnFe2O4 nanotubes and gel powders have been compared. The photovoltaic response threshold of the ZnFe2O4 nanotubes exhibited a blue-shift of about 150 nm with respect to that of the ZnFe2O4 gel powder, which implies that the photogenerated charges in the nanotubes have a higher redox activity than that of the gel powder. Both materials behave like a p-type semiconductor with photogenerated electrons accumulated at their surface. © 2009 Acta Materialia Inc. |
