Nanocomposite of Montmorillonite and ZnS Nanoparticles: Preparation and Application for Photocatalysis

Popis výsledku v původním jazyce

ZnS nanoparticles were immobilized in micro- and mesopores of the clay mineral montmorillonite (MMT). The resulting ZnS and MMT nanocomposite (ZnS-MMT) contained of about 6 wt. % of ZnS. The formation of ZnS-MMT particles was described by a mathematical model and was characterized by several methods, such as electron scanning (SEM) and transmission microscopy (TEM), X-ray diffraction (XRD), dynamic light scattering (DLS), UV-VIS diffusion reflectance (DRS) and photoluminescence spectroscopy (PLS), specific surface area and pore size measurements. ZnS nanoparticles were found to be firmly fixed in the MMT pores forming thea stable nanocomposite. The nanocomposite was used for several photocatalytic applications: the decomposition of phenol, the reduction of carbon dioxide, decomposition of nitrous oxide. ZnS-MMT was found to be more efficient than the commercially available TiO2 (Evonik P25). The results referred to in this chapter have been previously published in our eight peer-reviewed papers cited in References.
