Currently, mechanochemical degradation is considered a highly promising technology for the degradation of PFOA. This study systematically employs density functional theory (DFT) and the COGEF (COnstrained GEometry to simulate Forces) model to deeply investigate the impact of external forces on the degradation properties of PFOA molecules. Through quantum chemical calculations, we analyzed in detail the changes in the electronic structure, chemical reactivity, and decarboxylation reaction process of PFOA molecules under the influence of external forces. The results show that the application of external forces significantly alters the electronic density distribution of PFOA molecules, thereby enhancing their reactive activity, especially in terms of nucleophilicity and radical reactivity at the carboxylate end. Moreover, the application of external mechanical force reduces the Gibbs free energy change of the decarboxylation reaction, thereby making the reaction energetically favorable. This study not only theoretically elucidates the mechanism of mechanochemical degradation of PFOA, but also provides a basis for optimizing its mechanochemical degradation technology. In addition, this study also provides a systematic theoretical perspective for exploring the mechanisms of mechanochemical degradation.</p>","PeriodicalId":101140,"journal":{"name":"RSC Mechanochemistry","volume":" 5","pages":" 692-705"},"PeriodicalIF":0.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/mr/d5mr00048c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144929126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous work demonstrated using FT-IR spectroscopy that a mechanochemical reaction had occurred in the mechanically treated neat mixtures. Herein is reported that microcrystal electron diffraction (microED) afforded the discovery of two diffracting micron-size particles in the amorphous powder synthesized by manual grinding, among a majority of non-diffracting particles. Remarkably, microED data of one of them led to the known lattice parameters of quininium aspirinate. Furthermore, this so-called ‘X-ray amorphous’ phase quickly recrystallizes upon exposure to vapors of <em>N</em>,<em>N</em>-dimethylformamide, or hexane vapours (at a lower rate); but it remains amorphous for longer than 20 months when stored at ambient conditions in a closed container. The lattice parameters and the degrees of crystallinity of both recrystallized materials are identical within the experimental error. However, slightly more intense and better-resolved X-ray powder diffraction peaks are observed in the material recrystallized from <em>N</em>,<em>N</em>-dimethylformamide vapours than in the analogous phase recovered from hexane. As expected, Williamson–Hall graphs lead to a larger average crystalline domain size for the former solid.
