- Abstract
TiO/cellulose composite aerogels were easily fabricated by the in situ synthesis of TiO nanoparticles in a cellulose matrix at a mild temperature (≤80 °C). The TiO/cellulose aerogel structure and morphology were analyzed with scanning electron microscopy, transmission electron microscopy, X-ray diffraction, thermal gravimetric analysis, and nitrogen adsorption-desorption tests as well as tensile testing. The results revealed that the TiO content in the composite aerogels increased dramatically with an increase of the treating times in tetrabutyl titanate to achieve a value of 65 wt%, which was much higher than that in literatures. Depending on the number of hydrolysis cycles, the mean diameter of the TiO nanoparticles was controlled to be approximately from 1.5 ± 1.0 to 3.5 ± 2.0 nm. The TiO/cellulose nanocomposite aerogel exhibited excellent mechanical strength, good UV screening ability as well as highly efficient photo-catalytic activity under weak UV light irradiation. This work opens a new avenue to construct TiO/cellulose aerogels with a high content and small size of TiO nanoparticles, thus demonstrating potential applications in the fields of UV screening and catalyst.
