CHARACTERIZATION OF HYDRATED TITANIUM OXIDE WITH SHEET-LIKE AND TUBE-LIKE STRUCTURES PREPARED BY A HYDROTHERMAL PROCESSING

Hydrated titanium oxides structures have been synthesized successfully from rutile by a single-step hydrothermal process at 130 0C in NaOH at concentrations of 5 M and 10 M, monitoring up to two days. Field emission scanning electron microscopy (FEG-SEM) and transmission electron microscopy (TEM) im...
