“…The light source was a 500 W Xe-arc lamp (Nanjing Xujiang Machine-electronic Plant) equipped with wavelength cutoff filters (1 M sodium nitrite solution, λ ≥ 400 nm) used as visible light source [30]. At each time, 100 mg of the powdered photocatalyst was added into a 200 mL solution of MO dye (20 mg·L -1 rated by centrifugation at 12,000 rpm for 10 min.…”

Noble metal Ag nanoparticles with unique surface plasmon resonance property have attracted much attention recently in the field of photocatalysis. Based on the advantages of Ag nanoparticles and semiconductor CeO 2 , a novel plasmonic photocatalyst Ag-AgCl/CeO 2 was prepared with a facile route. The as-prepared samples were characterized using scanning and transmission electron microscopy, X-ray photoelectron spectroscopy and UV-vis diffusion reflection spectroscopy. This metal-semiconductor nanocomposite plasmonic photocatalyst exhibited a high visible-light photocatalytic activity and good stability for photocatalytic degradation of methyl orange in water. Ag-AgCl/CeO 2 will be a potentially promising plasmonic photocatalysts for organic pollutant degradation and water purification.

“…It was observed that the mixed oxide with Fe/Ce = 1 resulted in 13 % removal of phenol, 93 % removal of methylene blue and almost complete removal of congo red. The higher photocatalytic activity of the mixed oxide was attributed to its higher surface area and surface acidity, which determine the active sites of the photocatalyst thus accelerating the photocatalytic reaction [40][41][42][43][44][45].…”

ZnFe2O4/ZnO nanopowder was prepared by solution combustion method. The characterization of the nanopowder was done by powder X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. Powder X-ray diffraction pattern of the nanopowder exhibited the spinel phase of zinc ferrite and wurtzite phase of zinc oxide. The nanopowder was used for the photocatalytic removal of acid orange dye 7 from its aqueous solution. The effect of various factors such as initial dye concentration, dosage of the photocatalyst and irradiation time was studied. An analysis of the results indicated that the dye degradation was more in case of 10 and 20 ppm dye solutions. The dye degradation decreased with increasing initial concentration. ZnFe2O4/ZnO can be used as a better photocatalyst for the removal of dyes from their aqueous solutions.

“…Titania has high photoactivity and superior property in photoelectric conversion, while zinc ferrite is sensitive to visible light. So coupling of these two semiconductors may become a new type of composite having high utility of sunlight, high photoactivity and high efficiency of photoelectric conversion [7]. The development of such high efficient photocatalyst and its application on structures may make better results in reduction of NO2 concentration.…”

Abstract-Visible light photocatalytic degradation of nitrogen dioxide was studied using zinc ferrite titania as photocatalyst. A photocatalytic reactor was made up of concrete block and glass was fabricated for studying photocatalytic oxidation of NO2 under visible light. Zinc ferrite titania was prepared and it's particle size and band gap energy was found out by X-Ray Diffraction (XRD) study and UltravioletDiffusive Reflectance Spectrometry (UV-DRS) respectively. Catalyst was coated on the concrete block surface and NO2 was produced and pumped in to the reactor which was equipped with visible light source. Effect of catalyst dosage, irradiation time, light intensity and initial concentration of NO2 were studied in lab scale and optimum catalyst dosage and irradiation time was found to be 10 mg/cm 2 and 20 minutes respectively. The maximum removal efficiency was found to be 84% at optimum conditions. It was observed that removal efficiency of nitrogen dioxide increases as the light intensity increases and decreases as the initial concentration increases. Performance of zinc ferrite titania catalyzed photodegradation was evaluated in the field under direct sunlight and ambient NO2. Average removal efficiency of ambient NO2 was found to be 81% in the field
