Abstract Ti(OPr’), vapor was pyrolyzed in dry nitrogen atmosphere using a simple tubular flow reactor at 400 and 800°C. Well-defined spheroidal anatase TiO, particles showing mesoporous surfaces of 30 m2 g-r and assuming two different morphologies (fused and composite) were produced at the low temperature (ca. 4OO”Q whereas deformed spheroidal particles of rutile-structured TiO, and surfaces of 12 mZ g ... إقراء المزيد
