BaOx
(Bilkent University, 2011)In this work, formation anddecomposition pathways of of Ba(NO3)2 on BaOBaO2 /Pt(111) surfaces were investigated at the molecular levelfordifferent BaOBaO2coverages starting from small 2D islands of 0.5 MLE (MLE: ... -
BaOx/ Pt(111) AND BaOx/ TiO2/ Pt(111) MODEL CATALYSTS FOR UNDERSTANDING NOx STORAGE-REDUCTION (NSR) CATALYSIS AT THE MOLECULAR LEVEL
(Bilkent University, 2011)In this work, formation anddecomposition pathways of of Ba(NO3)2 on BaOBaO2 /Pt(111) surfaces were investigated at the molecular levelfordifferent BaOBaO2coverages starting from small 2D islands of 0.5 MLE (MLE: ... -
Ceria promoted NOx storage and reduction materials
(Bilkent University, 2011)In the current work, the effect of CeO2 promotion on the NOx storage materials and NOx storage-reduction (NSR) catalysts is studied. Synthesized materials were prepared using different baria and ceria loadings in order ... -
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 ... -
Investigation of NO2 and SO2 adsorption/desorption properties of advanced ternary and quaternary mixed oxides for DENOx catalysis
(Bilkent University, 2015-11)The main premise of the current study is the design, synthesis and functional characterization of novel catalytic materials with superior resistance against sulfur poisoning without compromising NOx storage capacity (NSC) ... -
NOx reduction on a transition metal-free γ-Al2O3 catalyst using dimethylether (DME)
(2008)NO2 and dimethylether (DME) adsorption as well as DME and NO2 co-adsorption on a transition metal-free γ-alumina catalyst were investigated via in-situ transmission Fourier transform infrared spectroscopy (in-situ FTIR), ... -
Spectroscopic investigation of sulfur-resistant Pt/K2O/ZrO2/TiO2/Al2O3 NSR/LNT catalysts
(Elsevier BV, 2016)An alternative ternary support oxide material and its K2O and Pt functionalized counterparts in the form of Pt/K2O/Al2O3/ZrO2/TiO2 with different K2O loadings were synthesized. Structural and morphological properties of ... -
Sulfur tolerance of Fe promoted BaO/Al2O3 systems as NOx storage materials
(Bilkent University, 2011)Ternary mixed oxide systems in the form of BaO/FeOx/Al2O3 were studied with varying compositions as an alternative to the conventional NOx storage materials (i.e. BaO/Al2O3). NOx uptake properties of the freshly prepared ... -
Trade-off between NOx storage capacity and sulfur tolerance on Al2O3/ZrO2/TiO2–based DeNOx catalysts
(Elsevier, 2019)Al2O3/ZrO2/TiO2 (AZT) ternary mixed oxides functionalized with Pt and BaO were synthesized in powder and monolithic forms and were utilized in NOx Storage Reduction/Lean NOx Trap (NSR/LNT) catalysis as novel catalytic ...
