Synthesis of anataseTiO_2 having high specific surface area from a gel precursor

摘要

Anatase TiO_2 having high temperature stability and specific surface area was synthesized using a gel precursor in very mild conditions. The precursor gel was obtained by dialysis treatment of Na_(16)Ti_(10)O_(28)-HNO_3 solution. The samples were characterized by X-ray diffraction analysis, transmission electron microscopy, Brunner-Emmett-Teller method for specific surface area measurements, and thermogravimetric analysis.
