Thanks to its high activity, high selectivity, and durability, Cu-CHA is commercialized as an NH3-SCR catalyst. Despite the superior catalytic performance, small amounts of nitrous oxide (N2O) are formed during the NH3-SCR as an unwanted by-product. N2O has a strong greenhouse potential and should be avoided. To further enhance the performance of NH3-SCR catalysts to handle the increasingly stringent emission standards, understanding the mechanism for NH3-SCR and, in particular, N2O formation over Cu-CHA is essential.</span><div><br /></div> <div>In this thesis, density functional theory (DFT) calculations and first principles microkinetic simulations are used to investigate the reaction path and the reaction kinetics for low temperature-NH3-SCR. Based on a previously proposed catalytic cycle for NH3-SCR over Cu-CHA, an N2O formation path is put forward. It is proposed that N2O can form over linear [Cu(NH3)2]+ complexes, which are present during low temperature operation. N2O is formed from H2NNO, which is generated via NH2-NO coupling over a Cu-OOH-Cu site. The reaction proceeds with a low barrier and rationalizes the low-temperature</div> <div>N2O emission peak observed experimentally at high Cu-loadings. N2O formation at high temperatures is instead proposed to occur through the decomposition of NH4NO3.</div> <div><br /></div> <div>With a catalytic cycle including N2O formation, a first principles microkinetic model is developed to investigate the reaction kinetic of NH3-SCR over Cu-CHA. When developing the model, special attention is paid assessing the change in entropy for each reaction step. The results from the kinetic model show good agreement with the experimental data of apparent activation energies, reaction orders and N2O selectivity. The model links the catalytic performance with structure and forms the basis for further developments of the NH3-SCR technology.</div> <div><br /></div></div>https://www.chalmers.se/en/research/strong/nano/calendar/Pages/ei_nano_seminar_6_dec.aspxhttps://www.chalmers.se/en/research/strong/nano/calendar/Pages/ei_nano_seminar_6_dec.aspxSmallTalks [about Nanoscience] Quantum Thermodynamics<p>KB, lecture hall, Kemigården 4, Kemi</p><p>​Welcome to a seminar in the series SmallTalks [about Nanoscience] arranged by the Excellence Initiative Nano​. Juliette Monsel from Applied quantum physics Lab, Department for Microtechnology and Nanoscience will talk about Quantum Thermodynamics. The title for the second part of this seminar will be announced soon.  Join from PC, Mac, Linux, iOS or Android: https://chalmers.zoom.us/j/63018620593 ​</p><a href="/SiteCollectionDocuments/SO%20Nano/SmallTalks/Decisiontree_EI_NanoSeminar2021_SC%203.pdf" style="outline:0px"><img src="/SiteCollectionImages/Areas%20of%20Advance/Nano/SmallTalk%20about%20Nanoscience/Decisiontree_EI_NanoSeminar2021_SC%203.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:207px;width:150px" />​</a><span style="background-color:initial">In c</span><span style="background-color:initial">ase you are not sure yet, whether you want to attend or not, we have prepared a decision tree that might help you! </span><div><span style="background-color:initial">Click to get a larger picture.</span><a href="/SiteCollectionDocuments/SO%20Nano/SmallTalks/Decisiontree_EI_NanoSeminar2021_SC%203.pdf">​</a><div><p class="chalmersElement-P"><br />​​</p></div></div> https://www.chalmers.se/en/centres/2d-tech/calendar/Pages/seminar-sofer.aspxhttps://www.chalmers.se/en/centres/2d-tech/calendar/Pages/seminar-sofer.aspxLayered materials beyond graphene – new possibilities and applications<p>Kollektorn, lecture room, Kemivägen 9, MC2-huset</p><p>Seminar with Prof. Zdenek Sofer, Department of Inorganic Chemistry, University of Chemistry and Technology Prague, Czech.  The seminar will be in hybrid format.

The research activities in the field of other layered materials like phosphorene, arsenene, silicene and germanene are rapidly growing in the last few years. Compare to graphene, all these materials are non-zero band-gap semiconductors. This property opens new application possibilities in electronic and optoelectronic devices. The properties of 2D materials can be further controlled by their functionalization. The chemistry of materials beyond graphene is none explored and shows high application potential in many fields. Compared to the graphene and pnictogen group, the chemical exfoliation method must be applied for synthesis of silicene / germanene derivatives using Zintl phase compounds like CaGe<sub>2</sub> and CaSi<sub>2</sub>. Various methods well known from organic chemistry can be applied for synthesis of <a name="OLE_LINK48"></a>tetrel derivatives reaching almost complete derivatization of 2D material skeleton.</span><span style="background-color:initial"> </span></p></div> <p class="chalmersElement-P"> </p>https://www.chalmers.se/en/research/strong/nano/calendar/Pages/ei_nano_seminar_24_jan.aspxhttps://www.chalmers.se/en/research/strong/nano/calendar/Pages/ei_nano_seminar_24_jan.aspxSmallTalks [about Nanoscience]<p>TBD</p><p>​​Welcome to a seminar in the series SmallTalks [about Nanoscience] arranged by the Excellence Initiative Nano​.
