Sunlight induced photo-thermal synergistic catalytic CO2 conversion via localized surface plasmon resonance of MoO3−x
Jue Li,Yinghao Ye,Liqun Ye,Fengyun Su,Zhaoyu Ma,Jindi Huang,Haiquan Xie,Dmitry E. Doronkin,Anna Zimina,Jan-Dierk Grunwaldt,Ying Zhou +10 more
TL;DR: In this article, oxygen vacancies are induced in MoO3 for improving photo-thermal CO2 reduction efficiency by capturing near-infrared (NIR) photons, which can promote the carrier separation, improve CO2 adsorption on the defective surface and lower the barrier of CO2 hydrogenation during the conversion process.
Journal ArticleDOI
Stabilizing Cu+ in Cu/SiO2 Catalysts with a Shattuckite-Like Structure Boosts CO2 Hydrogenation into Methanol
Jiafeng Yu,Meng Yang,Meng Yang,Jixin Zhang,Qingjie Ge,Anna Zimina,Tim Pruessmann,Lei Zheng,Jan-Dierk Grunwaldt,Jian Sun +9 more
TL;DR: The real evolution of the Cu species is still cove... as mentioned in this paper, and their performance highly depends on supports, and their real evolution is still a cove..., and they are widely employed for CO or CO2 hydrogenation into methanol.
Journal ArticleDOI
CAT-ACT-A new highly versatile x-ray spectroscopy beamline for catalysis and radionuclide science at the KIT synchrotron light facility ANKA.
Anna Zimina,Kathy Dardenne,Melissa A. Denecke,Dmitry E. Doronkin,E. Huttel,Henning Lichtenberg,Stefan Mangold,Tim Pruessmann,J. Rothe,Th. Spangenberg,Ralph Steininger,Tonya Vitova,Horst Geckeis,Jan-Dierk Grunwaldt +13 more
TL;DR: CAT-ACT augments present capabilities at the INE-Beamline by increasing the flux and extending the energy range into the hard X-ray regime, and combines state-of-the-art optics with a unique infrastructure for radionuclide and catalysis research.
Journal ArticleDOI
Hydrotreatment of Fast Pyrolysis Bio-oil Fractions Over Nickel-Based Catalyst
Caroline Carriel Schmitt,Klaus Raffelt,Anna Zimina,Bärbel Krause,Thomas Otto,Michael Rapp,Jan-Dierk Grunwaldt,Nicolaus Dahmen +7 more
TL;DR: In this article, the effects of upgrading on different fast pyrolysis bio-oil (FPBO) fractions obtained from a commercially available FPBO were studied by elemental analysis, GC-MS and 1H-NMR.
Journal ArticleDOI
Understanding sulfur poisoning of bimetallic Pd-Pt methane oxidation catalysts and their regeneration
Patrick Lott,Mario Eck,Dmitry E. Doronkin,Anna Zimina,Steffen Tischer,Radian Popescu,Stéphanie Belin,Valérie Briois,Maria Casapu,Jan-Dierk Grunwaldt,Olaf Deutschmann +10 more
TL;DR: In this paper, the performance of Pd-Pt/Al2O3 and Pt/CeO2-ZrO2/Zr O2-Y 2O3-La2O 3 methane oxidation catalysts was investigated under typical lean-burn gas engine conditions with respect to sulfur poisoning and during reactivation, particularly under the most efficient rich conditions.
