Abstract

A cellulose acetate/TiO2 composite was prepared by dissolving cellulose acetate in acetone:acetic acid (70:30 in volume) and adding quantities of titanium(IV) tert-butoxide to obtain varying oxide content after phase inversion, which was achieved by adding water to this mixture. Regardless the quantity of titanium(IV) tert-butoxide, were obtained composites containing about 4 wt.% of TiO2 as anatase, indicated by XRD and Raman spectroscopy. They showed thermal stability up to 250 °C. Adsorption isotherms of methylene blue revealed a maximum adsorption of 11 μmolg-1. This material proved to be an efficient catalyst for the photodegradation of MB under artificial or solar ultraviolet radiation.
