Abstract
U ovom je radu provedena sinteza i karakterizacija fotokatalizatora cinkovog oksida i kompozita cinkov oksid/lebdeći pepeo. Lebdeći je pepeo sluţio kao nosač katalizatora. Sinteza katalizatora provedena je na dva načina: sol-gel sintezom i in situ sintezom. Sintetizirani katalizator testiran je u fotokatalitičkim procesima za pročišćavanje otpadnih voda. Određeni su optimalni uvjeti pri kojima je fotokataliza bila najučinkovitija, a to su koncentracija katalizatora 1 g/l i pH vrijednost 7. Sintetizirani fotokatalizatori okarakterizirani su infracrvenom spektroskopijom s Fourierovom transformacijom (FTIR), rendgenskom difrakcijskom analizom (XRD), pretražnom elektronskom mikroskopijom (SEM) te je provedeno ispitivanje njihove fookatalitičke aktivnosti pri razgradnji azo-bojila Reactive Red 45 (RR45). Rezultati fotokatalitičke razgradnje ukazuju na učinkovito uklanjanje bojila pomoću sintetiziranih fotokatalizatora. Najveću fotokatalitičku učinkovitost pokazuje uzorak ZnO 1.
Abstract (english)
This work studies the synthesis and characterization of zinc oxide and nanocomposite zinc oxide/fly ash. Fly ash was used as a carrier of catalyst. Synthesis of catalyst was carried out by two procedures: sol-gel synthesis and in situ synthesis. Synthesized catalyst was tested in photocatalytic process for wastewater treatment. Optimal conditions in which the photocatalysis is most effective were determined as the concentration of catalyst of 1g/l and pH value 7. Synthesized catalysts were characterized with Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Furthermore, examination of catalysts' photocatalytic activity was studied in a process of azodye Reactive Red 45 (RR45) degradation. The results show that all synthesized catalysts efficiently remove RR45 pollutant from water. Catalyst ZnO 1 has the highest photocatalytic activity.
