- Abstract
- The present work demonstrates a facile, low cost and environmentally friendly technique for carburization of TiO2 nanotubes. XRD and XPS investigations suggest that the anodically grown self-organized TiO2 nanotubes when annealed in an argon filled steel nut-bolt cavity working as an autogenic pressure reactor undergo carburization at 650 degrees C, which converts TiO2 into TiOyCz. TEM-SAED suggests that the carburized nanotubes are polycrystalline, and also contain some reduced oxides of titanium. The conductivity measurement of the carburized nanotubes shows their conductivity to be close to metals. The electrochemical investigation of the carburized nanotubes demonstrates that the material can be used as a conductive electrode material for electrochemical reactions.
