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 {\ensuremath{>}}60\% toward CH4 with a production rate of 15 {\ensuremath{\mu}}mol.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.}, url = {http://dx.doi.org/10.1021/acs.nanolett.1c00677}, author = {Schofield, S and Bin Subhan, MK and Suleman, A and Moore, G and Phu, P and Hoesch, M and Kurebayashi, H and Howard, C}, keywords = {CO2 reduction, copper, boron nitride, interface, electrochemistry} }
