WebMar 3, 2024 · Methods. The ion-molecule reaction mechanism of CHCl •− with S 2 O and O 3 was studied using the DFT-BHandHLYP level of theory with the aug-cc-pVDZ basis set. Our theoretical findings show that Path 6 is the favored reaction pathway for CHCl •− + O 3 reaction as identified by the O-abstraction reaction pattern. WebDFT calculations of heterogeneous reactions on catalyst surfaces can provide valuable insights about the reactivity and mechanisms, allowing in silico screening and design of catalysts. Figure 1.
