Zinc sulphide nanoparticles for photochemical reactions: reduction of carbon dioxide and oxidation of phenol
Original language description
ZnS nanoparticles were prepared and deposited on montmorillonite (MMT) in the presence of cetyltrimethylammonium (CTA). Transmission electron microscopy (TEM) proved the formation of nanoparticles with diameters about 5 nm. The nanoparticles were deposited on MMT forming the ZnS-MMT-CTA nanocomposite that was used for the photochemical reactions of CO2 and phenol under UV light. The commercial TiO2 photocatalyst was used for comparison. The photoreduction of CO2 provided a considerably high efficiency that exceeded 5-6 fold the results with TiO2. The main reaction products were hydrogen and methane. The low concentrations of methanol and carbon monoxide were also determined. ZnS-MMT-CTA was also used for the photooxidation of phenol in its aqueous solutions. ZnS-MMT-CTA exhibited considerably higher efficiency than TiO2 and UV irradiation. The phenol oxidation according to pseudo-first reactions was observed. The gas chromatography and pH measurements suggested that phenol was oxidized
