... sensors, and so on [11–22].Functional properties of TiO2are influenced by many factorssuch as crystallinity, particle size, surface area, and preparation[11]. In the view point of surface area, ... by hydro-thermal and post heat-treatments from natural rutile sand,however, nanofibers TiO2had rather low surface area (10–20 m2/g) [32,33].In this study, high surface area nanosheet TiO2with ... 2006AbstractHigh surface area nanosheet TiO2with mesoporous structure were synthesized by hydrothermal method at 130 °C for 12 h. The samples werecharacterized by XRD, SEM, TEM, SAED, and BET surface area. ...
