Porous carbon obtained by the pyrolysis of TiO2/poly(furfuryl alcohol) nanocomposite: preparation, characterization and utilization for adsorption of reactive dyes from aqueous solution
| Summary: | This study reports the preparation of high surface area amorphous carbon by pyrolysis of TiO2/poly(furfuryl alcohol) nanocomposite. This nanocomposite was synthesized by hydrolysis of titanium tetra-isopropoxide/furfuryl alcohol mixture. All samples were characterized by XRD, FT-IR, Raman spectroscopy and transmission electron microscopy. The results indicated the effective FA polymerization on TiO2 (anatase) nanoparticles and polymer conversion to amorphous carbon after pyrolysis, simultaneously with TiO2 anatase-rutile phase transition. After the oxide nanoparticles dissolution by an aqueous HF solution the obtained carbon was extremely porous, with high surface area (700 m² g-1), similar to a carbon foam. With this new carbon material we carried out a study of kinetic of the adsorption of the reactive black 5 (RB5) azo-dye. |
