Abstract:

The high efficiency of ordered mesoporous carbon-based anatase for the visible light-driven photo-degradation of phenol in water is reported. Adsorption-photocatalysis cycles were used to treat polluted water. Contaminated water containing 200 mg/L phenol can be completely mineralized within 10 cycles, in which each cycle consisted of adsorption for 8 h and visible light-driven illumination for 8 h. The roles of non-metal doping in the anatase lattice, aggregation-free confinement of anatase nanoparticles by the carbon pore wall, and adsorption of phenol in the mesopores on the catalytic performance are discussed. The present work provides an effective combination of physical and chemical treatments to remove relatively high concentrations of non-biodegradable organic substances using a mesoporous photocatalyst.
