“…Also low costs of transition metal oxides make them more competitive than noble metal catalysts. Indeed, considerable interest has been paid to the development of oxide catalysts for VOC combustion in recent years [4][5][6][7][8][9][10]. In a previous work [11], we investigated the catalytic performance of Cu x O 1−x O y catalysts for acetone combustion.…”

“…They have been preferentially used in commercial practices in spite of their cost (Masui et al, 2010;Venezia et al, 2001). Among different noble metals, Pd and Pt have been widely studied for this purpose (Ö zc¸elik et al, 2009;Rahmani et al, 2014a). Pd is more active for oxidation of short-chain hydrocarbons, while Pt exhibits higher activity toward long-chain hydrocarbons and aromatics (Abbasi et al, 2011).…”

In this paper, CeO 2 (30%)/Clinoptilolite was synthesized via HNO 3 treatment and coprecipitation methods and then 1% Pt was dispersed over support by ultrasound assisted wet impregnation. The synthesized samples were characterized using XRF, XRD, FESEM, N 2 adsorption and FTIR techniques. The obtained results from XRD revealed the main phase in utilized clay is clinoptilolite and also formation of amorphous structure was proved after acid treatment. FESEM micrographs confirmed significant structural changes in clinoptilolite after acid treatment and also formation of ceria nanoparticles. N 2 adsorption presented large enough surface area for Pt/CeO 2 -Clinoptilolite nanostructured catalyst to be used for toluene oxidation. Finally, activity results indicated that synthesized nanostructured catalyst was highly active and stable and could eliminate more than 90% of toluene at 130°C. Utilizing inexpensive materials in synthesis and assisting ultrasound in dispersion of active phase have made Pt(1%)/CeO 2 (30%)-Clinoptilolite a nominee to be used for catalytic oxidation of toluene. ª 2015 The Authors.

Poly(acrylic acid)/montmorillonite (MMT) composites with various polymer contents were synthesized by in situ polymerization technique. The structure of obtained materials was characterized by powder X-ray diffraction and infrared spectroscopy (FTIR). It was found that only a limited amount of hydrogel could be introduced between the clay layers. The remaining part of polymer was deposited on the external surface of clay particles. The introduction of the polymer modifier significantly increased the adsorption capacity of MMT in the elimination of Fe 3?ions from aqueous solution. The thermal behavior of the samples before and after the Fe 3? adsorption was examined by thermogravimetry and differential thermal analysis. Moreover, the composition of gaseous products evolved during decomposition was determined by FTIR. The materials after Fe 3? adsorption exhibited different thermal stability in oxidizing atmosphere than the fresh samples. Fe 3? cations, forming FeO x species during thermal treatment, appeared to be effective catalysts of polymer oxidation.
