Photocatalytic activity of Fe/Ti-based compounds obtained from ferro-titaniferous mineral sands via a simple soft chemistry route

چکیده
Abstract Fe/Ti-based compounds were synthesized from ferro-titaniferous mineral sands using aqueous oxalic acid under subcritical water (sCW) conditions (135°C/50 bar/4 h) and their photocatalytic activity was evaluated against methylene blue or caffeine UV-A visible radiation. The X-ray diffraction Raman spectroscopy analyses revealed that the as-synthetized mainly comprised of ferrous oxalate, followed by titanium dioxide. This proved complete transformation precursor within 4 h acid/sCW as reaction medium. studies showed photodegraded radiation as-synthesized compounds. Methylene removal up to 92.8 97.4% after 6 hours irradiation, respectively. Caffeine removal, however, reached 69.3 59.6% 16 exposure light, can be potentially used a ferrous-based catalyst in heterogeneous photocatalysis for decontamination systems organic pollutants.
