Abstract

The photocatalytic activity of three different hybrid C-TiO2 nanostructured materials prepared by solvothermal synthesis was studied using phenol as test molecule under UV-visible irradiation. The influence of the origin of carbon was verified by using furfural, chitosan and saccharose as biomass precursors. Characterization was performed by N2 adsorption isotherms, FTIR, XRD, DR/UV-vis and SEM. XRD patterns showed that carbon precursor affects not only textural parameters such as surface area and pore size distribution but also clearly affects the crystalline framework of TiO2. In spite of the photocatlytic activity of C-TiO2 was lightly lower than that of TiO2-P25, the present results suggested that these materials can be potentially used as eco-friendly and low-cost photocatalysys.
