Sumario:Semiconductor-based photocatalysis is one of the favorable techniques for the wastewater treatment. Herein, we synthesized the activated carbon-decorated cerium dioxide (AC-CeO(2)) nanocomposites via the facile ultrasonication method by using the biomass-derived AC nanoflakes and the sonochemically-synthesized CeO(2) nanoparticles. The AC-CeO(2) nanocomposites exhibited the aggregated morphology with the AC nanoflakes-anchored CeO(2) nanoparticles. Since the hybridization of conductive AC and semiconductive CeO(2) would lead to the increased photocarrier transport and the reduced photocarrier recombination, during the photocatalytic reaction, the AC-CeO(2) nanocomposites showed the enhanced crystal violet dye-degradation efficiency up to 97.9 % within 135 min. The results suggest that the AC-CeO(2) nanocomposites hold promise as a prominent photocatalyst for future green environmental technology.
