DESCRIPTION:Prof. Carl Hoff will be holding an in-person only seminar title
 d ”Methods for Oxidizing a Nitrogen Oxide to Nitrate” on Friday\, Nove
 mber 4th at 3:30 PM in Cox Science Room 318. \n\n \n\nAbstract:\nNitrous o
 xide\, O=N=N\, is isostructural with O=C=O. They are both greenhouse gases
 \, but due in part to its longer atmospheric lifetime\, nitrous oxide is 3
 00 times worse as a pollutant. It’s removal as a pollutant is not mandat
 ed. That removal is most often done\, as in the BASF deNOx process by high
  temperature decomposition over a proprietary Pt catalyst. It removes N2O 
 but does not produce a useful product from what is in fact a high energy v
 aluable chemical.\n\n\nIt is not easy to derivatize nitrous oxide to a use
 ful product. On January 15\, 2021 the first successful oxidation of nitrou
 s oxide to nitrate was discovered by us as shown in eqn. (1) (ACS Omega 20
 21\, 6\, 28\, 18248–18252)\n\n\n5 N2O + Na2O + 2 KCl → 2NaCl + 2 KNO3+
  4N2  (1)\n\n \n\nThe initial yields of nitrate were low-on the order of 
 ≈ 20%. Since that time considerable progress has been made. It seems pos
 sible that this work may ultimately be developed into a commercial process
 . On October 20\, 2022 a PCT patent application was published PCT/US22/250
 03. The simple reaction shown in eqn. (1) is considerably more complicated
  than it would appear. It occurs at room temperature and low pressure in a
  mixer mill. Additional potentially catalytic materials are added to the r
 eaction. Our current understanding of the reaction will be discussed. Supp
 ort by the Department of Energy DOE-BE-SDE-SC0019456 and KONOX-LLC is grat
 efully acknowledged.\n\n \n\n \n\nYour attendance is greatly appreciated!\
 n\nThank you and have a great day!
