Abstract

Nano-rutile-titania has been synthesized via a sol-gel route using titanium tetra n-butoxide as the precursor and ethyl alcohol as the solvent at a low temperature of 80 °C. When synthesized with HCl as the catalyst, the powders crystallized without calcination, while the materials prepared using acetylacetone as the catalyst required heating to ∼300°C to initiate the crystallization. The anatase to rutile transformation temperature decreased with increasing water content.
