“…However, this approach mainly focused on defect evolution, with limited attention to hydrogen−defect interactions. 18 In summary, quantitative methods and mechanisms for describing hydro- gen−defect interactions in nanoscale oxide films postinfiltration remain elusive. This study focused on rutile and anatase TiO 2 , where plasma bombardment prefabricated defects using N 2 and O 2 plasmas, generating distinct defect types as depicted in Figure 1.…”
