However, the practical application of this process is limited by its poor selectivity due to scaling relations. Here we introduce the rational design of the monolayer hexagonal boron nitride/copper (h-BN/Cu) interface to circumvent scaling relations and improve the electrosynthesis of CH4. This catalyst possesses a selectivity of >60% toward CH4 with a production rate of 15 μmol·cm–2·h–1 at −1.00 V vs RHE, along with a much smaller decaying production rate than that of pristine Cu. Both experimental and theoretical calculations disclosed that h-BN/Cu interfacial perimeters provide specific chelating sites to immobilize the intermediates, which accelerates the conversion of *CO to *CHO. Our work reports a novel Cu catalyst engineering strategy and demonstrates the prospect of monolayer h-BN contributing to the design of heterostructured CO2 reduction electrocatalysts for sustainable energy conversion. date: 2021-09-01 date_type: published publisher: American Chemical Society official_url: http://dx.doi.org/10.1021/acs.nanolett.1c00677 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1873496 doi: 10.1021/acs.nanolett.1c00677 lyricists_name: Howard, Christopher lyricists_name: Kurebayashi, Hidekazu lyricists_name: Schofield, Steven lyricists_id: CAHOW21 lyricists_id: HKURE44 lyricists_id: SSCHO23 actors_name: Schofield, Steven actors_id: SSCHO23 actors_role: owner full_text_status: public publication: Nano Letters: a journal dedicated to nanoscience and nanotechnology citation: Schofield, S; Bin Subhan, MK; Suleman, A; Moore, G; Phu, P; Hoesch, M; Kurebayashi, H; Schofield, S; Bin Subhan, MK; Suleman, A; Moore, G; Phu, P; Hoesch, M; Kurebayashi, H; Howard, C; - view fewer <#> (2021) Charge density waves in electron-doped molybdenum disulfide.
