Template synthesis of porous titania using cellulose nanocrystals
Porous titania with anatase structure has been prepared by a template process with cellulose nanocrystal (CNXL). Air-stable titanium(IV) bis(ammonium lactate)dihydroxide (Tyzor-LA) solution forms Tyzor-LA-CNXL composite upon adding CNXL colloids through interaction between Tyzor-LA and hydroxyl groups of CNXL. The Tyzor-LA-CNXL composite shows rod-like structures of 150-200 nm in length and 5-10 nm in diameter. After calcination at 500oC in air the composite showed anatase with porous structures and 170-200 m2/g specific surface area. X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), FT-IR, scanning electron microscope (SEM), and transmission electron microscope (TEM) were employed to characterize the morphologies and porous structures of the as-prepared and calcined composite mateials.
