In this study, porous titania nanoparticles were synthesized by sol–gel template method, using titanium (IV) tetraisopropoxide as a starting precursor and isopropanol as a solvent. Different commercial activated carbons were used as templates at 10 wt% in titania sol. The templates were completely removed during the calcination in air at 500 °C for 3 h, forming porous titania. Nanocrystalline anatase titania with specific surface area as high as 700 m2/g was successfully obtained in this study. This specific surface area is one of the highest values reported in the literature under similar sol–gel conditions.
► Nanocrystalline anatase with specific surface area as high as 700 m2/g was successfully obtained. ► We succeeded one of the highest specific surface area titania reported in the literature under simple sol–gel synthesis. ► Activated carbon template retarded the anatase-to-rutile transformation. ► Activated carbon template retarded the crystallite growth of titania.
