Enhanced sulfur tolerance of ceria-promoted NOx storage reduction (NSR) catalysts: sulfur uptake, thermal regeneration and reduction with H2(g)
(Springer New York LLC, 2013)SOx uptake, thermal regeneration and the reduction of SOx via H2(g) over ceria-promoted NSR catalysts were investigated. Sulfur poisoning and desulfation pathways of the complex BaO/Pt/CeO2/Al2O3 NSR system was investigated ... -
Finding an optimum surface chemistry for [Formula] systems as NOx storage materials
(Bilkent University, 2010)Titania promoted NOx storage materials in the form of BaO/TiO2/Al2O3 were synthesized via two different sol-gel preparation techniques, with varying surface compositions and morphologies [1, 2]. The influence of the TiO2 ... -
Palladium doped perovskite-based NO oxidation catalysts: the role of Pd and B-sites for NOx adsorption behavior via in-situ spectroscopy
(Elsevier, 2014)Perovskite-based materials (LaMnO3, Pd/LaMnO3, LaCoO3 and Pd/LaCoO3) were synthesized, characterized (via BET, XRD, Raman spectroscopy, XPS and TEM) and their NOx (x = 1,2) adsorption characteristics were investigated ... -
Photocatalytic NOx oxidation and storage under ambient conditions for air purification
(Bilkent University, 2012)Air pollution is one of the most serious environmental problems in both urban and rural settings with a direct impact on human health. A variety of chemical compounds can be associated with air pollution and gaseous ... -
Sulfur poisoning and regeneration behavior of perovskite-based NO oxidation catalysts
(Springer New York LLC, 2017)SOxuptake and release properties of LaMnO3, Pd/LaMnO3, LaCoO3and Pd/LaCoO3perovskites were investigated via in situ Fourier transform infrared (FTIR) spectroscopy, temperature programmed desorption and X-ray photoelectron ... -
TiO2-Al2O3 binary mixed oxide surfaces for photocatalytic NOx abatement
(Elsevier, 2014)TiO2-Al2O3 binary oxide surfaces were utilized in order to develop an alternative photocatalytic NOx abatement approach, where TiO2 sites were used for ambient photocatalytic oxidation of NO with O2 and alumina sites were ... -
Utilization of reducible mixed metal oxides as promoters for the enhancement of sulfur regeneration in nsr catalysts
(Bilkent University, 2016-08)Pt functionalized binary, ternary, and quaternary oxides (e.g. Pt/BaO/CeO2/ZrO2/Al2O3) were synthesized by wetness impregnation method and characterized by X-ray Diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area ...
