Preparation and characterization of high surface area nanosheet titania with mesoporous structure

摘要

High surface area nanosheet TiO_2 with mesoporous structure were synthesized by hydrothermal method at 130℃ for 12 h. The samples were characterized by XRD, SEM, TEM, SAED, and BET surface area. The nanosheet structure was slightly curved and approximately 50-100 nm in width and several nanometers in thickness. The as-synthesized nanosheet TiO_2 had an average pore diameter about 3-4 nm. The BET surface area and pore volume of the sample are about 642 m~2/g and 0.774 cm~3/g, respectively.
