- Abstract
- Semiconductor-based photocatalysis is one of the favorable techniques for the wastewater treatment. Herein, we synthesized the activated carbon-decorated cerium dioxide (AC-CeO2) nanocomposites via the facile ultrasonication method by using the biomass-derived AC nanoflakes and the sonochemically-synthesized CeO2 nanoparticles. The AC-CeO2 nanocomposites exhibited the aggregated morphology with the AC nanoflakesanchored CeO2 nanoparticles. Since the hybridization of conductive AC and semiconductive CeO2 would lead to the increased photocarrier transport and the reduced photocarrier recombination, during the photocatalytic reaction, the AC-CeO2 nanocomposites showed the enhanced crystal violet dye-degradation efficiency up to 97.9 % within 135 min. The results suggest that the AC-CeO2 nanocomposites hold promise as a prominent photocatalyst for future green environmental technology.
