      Kinetics of NH3 Desorption and Diffusion on Pt: Implications for the Ostwald Process. 

      Borodin, Dmitriy; Rahinov, Igor; Galparsoro Larraza, Oihana; Fingerhut, Jan; Schwarzer, Michael; Golibrzuch, Kai; Skoulatakis, Georgios; Auerbach, Daniel J.; Kandratsenka, Alexander; Schwarzer, Dirk; Kitsopoulos, Theofanis N.; Wodtke, Alec M. (American Chemical Society, 2021-10-21)
      We report accurate time-resolved measurements of NH3 desorption from Pt(111) and Pt(332) and use these results to determine elementary rate constants for desorption from steps, from (111) terrace sites and for diffusion ...

      Steric Hindrance of NH3 Diffusion on Pt(111) by Co-Adsorbed O-Atoms 

      Borodin, Dmitriy; Galparsoro Larraza, Oihana; Rahinov, Igor; Fingerhut, Jan; Schwarzer, Michael; Horandl, Stefan; Auerbach, Daniel J.; Kandratsenka, Alexander; Schwarzer, Dirk; Kitsopoulos, Theofanis N.; Wodtke, Alec M. (American Chemical Society, 2022)
      A detailed velocity-resolved kinetics study of NH3 thermal desorption rates from p(2 x 2) O/Pt(111) is presented. We find a large reduction in the NH3 desorption rate due to adsorption of O-atoms on Pt(111). A physical ...
