摘要
Calcination of cyclopentadienyltitanium-based organic-inorganic hybrid materials at 450-500 degrees C led to the formation of anatase titanium dioxide as white powders consisting of a porous network of aggregated nanoparticles, the nanoporosity detected being related to the inter-particle space. Depending on the calcination temperatures, the surface area of the titanium dioxide particles varied from 65 to 158 m(2) g(-1).
