The effect of sintering temperatures of TiO2(B)-nanotubes on its microstructure

Abstract

Titanium dioxide (TiO 2)-nanotubes were prepared by a simple technique reflux. The morphologies and microstructures of nanotubes were characterized by high resolution scanning electron microscopy (HRSEM), high resolution transmission electron microscopy (TEM), powder X-ray diffraction (XRD,) energy dispersive X-ray spectroscopy (EDS) and surface area analyzer. The microstructures of TiO 2 phases obtained from the sintering process of TiO 2-nanotubes for 1 hour at various temperatures from 100 to 1000 °C at intervals of 50 °C were investigated from the XRD diffractograms. The analyses of morphologies and microstructures from HRSEM and HRTEM images describe the sample as nanotubes. The nanotube is single phase exhibiting TiO 2 (B) structure. The XRD patterns show that TiO 2 (B)-nanotubes transform into anatase phase and then become rutile due to increasing sintering temperatures.

“…The Barrett Joyner and Halden (BJH) technique can be used to determine the specifi c pore volume (cm 3 /g), the average pore diameter, and the pore size distribution. (Sutrisno et al, 2018). The pore volume (V), the pore diameter (D), and the pore size distribution were determined by the graph drawn between quantity adsorbed (cm 3 /g STP) is given in Figure 7 and in Table 3.…”
