초록
Ceramic ZnS nanocomposites were prepared by mechanical processing and one-step heat sintering with powder mixtures offly ash, waste glass, and ZnS (template-free hydrothermal method manufacturing). Chemical durability and morphologicalcharacteristics of heat-treated samples at 800 oC with/without acid treatment were evaluated. The photocatalytic activities wereestimated with methyl orange (MO), methylene blue (MB), acetaldehyde (ATA), and 2,4-dichlorophenoxyacetic acid (2,4-D) asphotodegradation targets. Crystallization behaviors of the prepared ceramic ZnS nanocomposites were investigated using Xraydiffraction (XRD), field emission-scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectrometry(EDS). In addition, compressive and bending strength as mechanical properties were evaluated. Ceramic ZnS nanocompositeswere found to showed improvement in optimal photocatalytic reaction and physical properties regardless of acid treatmentwhen the amount of ZnS nanoparticles was increased from 7.0 to 25.0 wt%. Degrees of photocatalytic decomposition of MO,ATA, 2,4-D, and MB by acid treated ceramic ZnS nanocomposites containing 25 wt% ZnS were about 0.185, 0.121, 0.216,0.236, respectively, after UV irradiation for 180 min.
