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 ... -
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), ... -
Passivation of type II InAs / GaSb superlattice photodetectors with atomic layer deposited Al2O3
(SPIE, 2012)We have achieved significant improvement in the electrical performance of the InAs/GaSb midwave infrared photodetector (MWIR) by using atomic layer deposited (ALD) aluminium oxide (Al2O3) as a passivation layer. Plasma free ... -
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 ... -
ZnO, TiO² and exotic materials for low temperature thin film electronic devices
(Bilkent University, 2012)The metal-oxide-semiconductor field-effect transistor (MOSFET) technology is the core of integrated circuit industry. Nearly all electronic devices around us contain transistors for various purposes like electronic ...
