However, the practical application of these catalysts is often impeded by challenges such as sintering-induced instability and poisoning of isolated atoms due to strong gas adsorption. In this study, we employed the mechanochemical method to insert single Cu atoms into the subsurface of Fe2O3 support. By manipulating the location of single atoms at the surface or subsurface, catalysts with distinct adsorption properties and reaction mechanisms can be achieved. It was observed that the subsurface Cu single atoms in Fe2O3 remained isolated under both oxidation and reduction environments, whereas surface Cu single atoms on Fe2O3 experienced sintering under reduction conditions. The unique properties of these subsurface single-atom catalysts call for innovations and new understandings in catalyst design. date: 2024-10-14 date_type: published publisher: Wiley official_url: https://doi.org/10.1002/anie.202410457 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2297112 doi: 10.1002/anie.202410457 medium: Print-Electronic lyricists_name: Regoutz, Anna lyricists_id: AREGO48 actors_name: Regoutz, Anna actors_id: AREGO48 actors_role: owner full_text_status: public publication: Angewandte Chemie International Edition volume: 63 number: 42 article_number: e202410457 event_location: Germany citation: Guan, Xuze; Han, Rong; Asakura, Hiroyuki; Wang, Bolun; Chen, Lu; Yan, Jay Hon Cheung; Guan, Shaoliang; ...
