Short Time Synthesis of Titania Nanotubes: Effect of Pre-Mixing Prior Hydrothermal

Indonesian Journal of Chemistry, 2019
The effect of pre-mixing by mechanical stirring before hydrothermal and hydrothermal time on the crystalline phases and morphology of titania has been studied. It was shown that nanotubes titania can be obtained after 5 h hydrothermal at 150 °C.

Two-phase Titania Nanotubes for Gas Sensing

Procedia Engineering, 2014
AbstractOur work reports the growth of two-phase (anatase-rutile) TiO2 nanotubes and the investigation of their gas sensing properties. Well-aligned and highly ordered nanotubes have been obtained by means of electrochemical anodization method. Depending on annealing regimes, the crystal structure of nanotubes was changing from anatase to anatase ...
