| Popis: | Nano-ZnO/regenerated cellulose (NZRC) films were prepared via the formation of Zn5(OH)8Cl2·H2O/regenerated cellulose (ZHCRC) film from cellulose-ZnCl2 aqueous solution by using NaOH aqueous solution as both the regeneration agent and the reactant, and the subsequent transformation of the Zn5(OH)8Cl2·H2O into nano-ZnO at a low hydrothermal temperature of 100 °C. The morphology of nano-ZnO changed from hexagonal nanosheets to nanorods as the hydrothermal treatment extending from 0.5 to 4 h. The NZRC films exhibited excellent photocatalytic degradation efficiency for methyl orange and 1.53 × 10−5 mol methyl orange was completely degraded in 40 min by using 1 g of hexagonal catalyst. The NZRC film photocatalytic composites can be applied in the large-scale industrial treatment for degrading organic dye wastewater with good prospects. |
