Traditionally, these 2D catalyst heterostructures were prepared by depositing a 2D material onto a pristine metallic surface. Preparing well-defined 2D monolayers, instead, on metal-oxide surfaces is challenging, although it is possible via O2 intercalation by oxidizing a metal substrate underneath. Several studies demonstrate this intercalative behavior of 2D covers, however, without the preparation of ordered structures, which are imperative for defining fundamental reaction mechanisms in confined space. We report the successful preparation and characterization of a well-defined, ultrathin cuprous oxide-like film grown between h-BN and Cu(111). The confined surface oxide adopts a “Cu2O-like” structure resembling the well-studied “44” Cu2O structure, although the oxidation temperature is surprisingly lower than its uncovered oxide counterpart and the h-BN layer remains intact following oxidation. Our experimental results, backed by theoretical simulations, outline the development of a heterostructure with an h-BN/metal-oxide interface as a model system, utilizing a preparation method likely transferable to a wide range of 2D/metal heterostructures and opening the door to new catalyst designs. date: 2024-03-28 date_type: published publisher: American Chemical Society official_url: http://dx.doi.org/10.1021/acs.jpcc.3c07828 full_text_type: other language: eng verified: verified_manual elements_id: 2263332 doi: 10.1021/acs.jpcc.3c07828 lyricists_name: Al-Hamdani, Yasmine lyricists_id: YSALH17 actors_name: Kalinowski, Damian actors_id: DKALI47 actors_role: owner funding_acknowledgements: 200020_172641 [H2020 Marie Sklodowska-Curie Actions]; 200020_200303 [H2020 Marie Sklodowska-Curie Actions]; [Swiss National Science Foundation]; FP-RESOMUS - MSCA 801459 [National Center of Competence in Research (NCCR) Molecular Ultrafast Science and Technology (MUST)]; X03DA [National Center of Competence in Research (NCCR) Molecular Ultrafast Science and Technology (MUST)]; [European Union]; s965 [Solid-Liquid Interface Chamber (SLIC)]; s1198 [Solid-Liquid Interface Chamber (SLIC)]; [Swiss National Supercomputing Centre (CSCS)]; [Alfred Werner Legat] full_text_status: restricted publication: The Journal of Physical Chemistry C volume: 128 number: 12 pagerange: 5156-5167 pages: 12 citation: Diulus, JT; Novotny, Z; Dongfang, N; Beckord, J; Al-Hamdani, Y; Comini, N; Muntwiler, M; ...
