HCHO prefers to react with NH3 to form HCN as the main product, leads to the decrease of NOx conversion and N2 selectivity. In situ FTIR reveals that the high surface acidity of catalyst will create a large enough of NH3 adsorbents for the reaction of HCHO to form HCONH2. In addition, in situ EPR experiments indicate that the high redox property of catalyst also facilitates the rate of HCONH2 formation.<eng> vorgelegt von Anh Binh Ngo GutachterInnen: Angelika Brückner (Department of Catalytic In-situ Studies, Leibniz Institute for Catalysis, University of Rostock, Germany) ; Sven Kureti (Institute for Energy Process Engineering and Chemical Engineering, Technical University of Bergakademie Freiberg) Dissertation Universität Rostock 2021 500 540 660 660.2995 660 35.17 http://purl.uni-rostock.de/rosdok/id00003764 https://doi.org/10.18453/rosdok_id00003764 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00003764-8 https://d-nb.info/1293537993/34 Effect of formaldehyde on selective catalytic reduction of nitrogen oxides by ammonia on V2O5-WO3/TiO2 catalysts--(DE-627)1759898422 urn:nbn:de:gbv:28-rosdok_id00003764-8 doi: 10.18453/rosdok_id00003764 oclc: 1333922166 ppn: (DE-627)1808688511
