Template Assisted Fabrication of TiO2 and BaTiO3 Nanotubes

摘要

This paper discussed fabrication of TiO2 and BaTiO3 nanotubes by sol-gel method and used anodic aluminum oxide (AAO) as template.The mechanical properties of TiO2 or BaTiO3 NTs are not great,so a longer tube can crack easily,leading to the peeling offofthe NTs film from the Ti substrate.Therefore,we propose to use AAO as a template,followed by deposition of TiO2 and BaTiO3 NT inside AAO to make a working electrode for further electronic devices.
