A Kinetic Monte Carlo Simulation on Fischer-Tropsch Synthesis to Model the Effect of Hydrogen Dynamics on Product Selectivity Uyhan, Merve Ceren; Üner, Necip Berker; Üner, Deniz (2025-09-05)
Tracking the Mode of Carbon Deposition During Dry Reforming of Methane over Ni/γ-Al2O3 Ay, Hale; Mao, Haiyan; Xu, Jun; Reimer, Jefferey A.; Üner, Deniz (2025-01-01) Dry reforming of methane was studied over Ni/Al2O3 catalyst at 600 °C with varying CO2/CH4 ratios (0.2, 0.5, 1, 2, 5). 13CO2 as well as 12CO2 were used along with 12CH4 and resulting carbon was characterized with 13C solid...
Process Intensification of Air Separation and Autothermal Bi-reforming Reactions Enabled by MnO/Mn2O3 Redox Pair Bak, Y. Gorkem; Ergül, S. Deniz; Oǧulgönen, C. Güvenç; Üner, Deniz (2025-01-01) In this work, the potential use of solar irradiation is investigated toward driving endothermic chemical looping reactions during reversible use of metal oxides, where endothermic processes were enablers of long-term stora...
Dissociation of HNO3 in water revisited: experiment and theory Munar, Ipek; Özer, Melike Özkan; Fusco, Edoardo; Üner, Deniz; Aviyente, Viktorya; Bühl, Michael (2024-01-01) Nitric acid dissociation in water is studied as a function of concentration, employing experimental techniques (1H NMR spectroscopy and calorimetry), quantum chemical methods (B3LYP and PBE functionals for molecular cluste...
LaCoO3 is a promising catalyst for the dry reforming of benzene used as a surrogate of biomass tar Çağlar, Başar; Üner, Deniz (2024-01-01) Tar build-up is one of the bottlenecks of biomass gasification processes. Dry reforming of tar is an alternative solution if the oxygen chemical potential on the catalyst surface is at a sufficient level. For this purpose,...
Effects of dead volume and inert sweep gas flow on photocatalytic hydrogen evolution over Pt/TiO2 Can Özcan, Elif; Üner, Deniz; Yildirim, Ramazan (2024-01-01) In this study, the effects of dead volume and sweep gas flow rate on photocatalytic hydrogen production over Pt/TiO2 were examined to determine their possible impact on hydrogen production rates. Five different dead volume...
PdH α-phase is associated with residual oxygen as revealed by in situ 1H NMR measurements and DFT-NMR estimations Mete, Ersen; Yılmaz, Begüm; Üner, Deniz (2023-12-30) An experimental and DFT study was conducted to investigate the chemical nature of α and β PdH phases in Pd/TiO2 through the detailed analysis of their 1H NMR chemical shifts. α-PdH states are identified with shielded 1H NM...
NMR spektroskopisi ile katalizör katakterizasyonu çalışmaları Üner, Deniz (2023-09-11)
In search of the bottlenecks of ammonia synthesis over Ru/Vulcan under ambient conditions ASLAN, MUSTAFA YASİN; Mete, Ersen; Üner, Deniz (2023-07-01) Hydrogenation of the N-N bond under ambient conditions over 1 wt% Ru/Vulcan was monitored through operando Diffuse Reflectance Infrared Spectroscopy (DRIFTS) and DFT. IR signals centered at 3017 cm(-1) and 1302 cm(-1) were...
