摘要：
Nanosized titanium oxide with anatase structure holding high surface area has been synthesized by the sol-gel route from an aqueous solution of titanyl sulfate. A stable titania sol with extremely narrow range of particles having an average size of 30 nm has been obtained. The crystalline anatase particles have average particle size of 5-10 nm and specific surface area of 375-104 m(2) g (-1) between the calcination temperature 200-600 degreesC. The powders were characterized by XRD, FTIR, TGA/DTA and N-2 adsorption analysis. (C) 2002 Elsevier Science B.V. All rights reserved.
