Sažetak
One of the innovative methods of water purification from organic pollutants is based on the photocatalytic ability of semiconductors such as zinc oxide (ZnO) [1]. With this study we will present photocatalytic properties of hybrid materials based on: a) cellulose and zinc oxide (ZnO), and b) ZnO structures obtained by thermal decomposition of the previously prepared ZnO/cellulose hybrids. We synthesized ZnO on two different cellulose substrates, Sodra Green T and UPM Conifer, using the plasma-enhanced atomic layer deposition (PE-ALD) method. After synthesis, the hybrid materials were calcinated in the furnace to obtain pure ZnO. We used field emission scanning electron microscope (FE-SEM) and X-ray photoelectron spectroscopy (XPS) for the characterization of the given samples. Methyl orange (MO) was used, as an organic dye, to examine the photocatalytic properties of the samples. FE-SEM images revealed that calcinated samples have porous tubular structures that are characterized by large specific surfaces. XPS spectra showed that ZnO which was synthesized on Sodra Green T cellulose has a larger amount of reactive OH groups indicating better photocatalytic activity. After calcination of the hybrid materials, ZnO showed enhanced photocatalytic properties. Within 80 min there is complete mineralization and decolorization of MO solution. Furthermore, ZnO deposited on Sodra Green T cellulose substrate proved to be a better photocatalyst than ZnO deposited on UPM Conifer cellulose substrate.
