| dc.description.abstract | Structurally layered mica has attracted much attention of the mineralogists due to its unique structural properties. This study mainly concerns in developing the nano-seeds of Zinc oxide on thin film of mica (ZnO-mica) and the potential study of the photo-catalytic property under UV-light irradiation. The ZnO-mica was prepared by the In-situ growth of nanoparticles. 5 g of (0.5 cm × 0.5 cm) cut thin films of mica was added to the mixture of 600 µL, 50 mL of Cetyltrimethylammonium chloride (CTAC) and 2 mol dm-3, 50 mL of zinc nitrate hexahydrate. Then, Zn(OH)2 seeds were grown on the thin sheets of mica by adding 4 mol dm-3, 50 mL of NaOH solution with stirring for 24 hrs. The obtained product was then calcined at about 600 ℃. Finally, photo-catalytic property study was carried out in beakers containing 50 mL of Methylene Blue (MB) with various dose of (1.0, 3.0, 4.0 and 10.0 g) ZnO-mica. UV-Vis spectroscopy analysis was implemented with 30 min of time interval under the UV-light irradiation with initializing under dark condition for 30 min to 3.5 hrs. The synthesized final product was characterized by using the characterizing techniques such as X-ray powder diffraction and scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy and thermo gravimetric analysis. The analytical data from the SEM reveal that the synthesized product with flower-like morphology having average particle length and width are 800 nm and 50 nm respectively. The crystallinity and the chemical analysis using XRD and FT-IR confirm the presence of ZnO on mica. The plot of percentage dye degradation versus time with increasing dosage under UV light indicates the rapid photo-catalytic dye degradation with increasing dosage of the photo-catalyst. The simple, flexible and novel method has been devised to develop the photo-catalyst under the UV-light irradiation. | en_US |
