Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 3,   Pages 405-416 doi: 10.1007/s11705-016-1579-x

Abstract: A sol-gel technique has been developed for the synthesis of a magnetite-silica-titania (Fe O -SiO -TiO ) tertiary nanocomposite with improved photocatalytic properties based on the use of inexpensive titania and silica precursors. The exceptional photocatalytic activity of the resulting materials was demonstrated by using them to photocatalyze the degradation of methylene blue solution. The best formulation achieved 98% methylene blue degradation. An interesting feature of the present work was the ability to magnetically separate and reuse the catalyst. The efficiency of the catalyst remained high during two reuses. The synthesized nanomaterials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, ultra-violet-visible spectroscopy, diffuse reflectance spectroscopy, and thermogravimetric analysis. XRD analysis revealed the formation of multicrystalline systems of cubic magnetite and anatase titania crystals. SEM and TEM characterization revealed well-developed and homogeneously dispersed particles of size less than 15 nm. FTIR spectra confirmed the chemical interaction of titania and silica. It was further noticed that the optical properties of the prepared materials were dependent on the relative contents of their constituent metal oxides.

Complete oxidation of methane on CoO-SnO catalysts

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 3,   Pages 265-270 doi: 10.1007/s11783-009-0019-2

Abstract: CoO-SnO hybrid oxides were prepared by the coprecipitation method and were used to oxidate methane (CH) in presence of oxygen. The CoO-SnO with a molar ratio of Co/(Co+Sn) at 0.75 exhibited the highest catalytic activity among all the CoO-SnO hybrid oxides. Experimental results showed that the catalysts were considerably stable in the CH combustion reaction, and were verified by X-ray photoelectron spectra (XPS). It was found that CoO was the active species, and SnO acted as a support or a promoting component in the CoO-SnO hybrid oxides. The surface area was not a major factor that affected catalytic activity. The hydrogen temperature-programmed reduction (H-TPR) results demonstrated that the interaction between cobalt and tin oxides accelerated the mobility of oxygen species of CoO-SnO, leading to higher catalytic activity.
