| description | Carbon aerogels (CA) derived from bamboo cellulose fibers were coupled with TiO<sub>2</sub> to form CA/TiO<sub>2</sub> hybrids, which exhibited extraordinary performance on the photo-catalytic degradation of methylene blue (MB). The structure and morphology of CA/TiO<sub>2</sub> were characterized by field emission scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Raman spectrum. The CA displayed a highly porous and interconnected three-dimensional framework structure, while introducing the catalytic active sites of TiO<sub>2</sub> onto the aerogel scaffold could remarkably enhance its photo-catalytic activity. The adsorption and photo-catalytic degradation of MB by the CA/TiO<sub>2</sub> hybrid were investigated. The maximum adsorption capacity of CA/TiO<sub>2</sub> for MB was 18.5 mg/g, which outperformed many similar materials reported in the literature. In addition, compared with other photo-catalysts, the present CA/TiO<sub>2</sub> demonstrated superior photo-catalytic performance. Almost 85% of MB in 50 mL solution with a MB concentration of 10 mg/L could be effectively degraded by 15 mg CA/TiO<sub>2</sub> in 300 min. |
