Grain Boundary-Rich Copper Nanocatalysts Generated from Metal-Organic Framework Nanoparticles for CO₂ -to-C₂₊ Electroconversion.

ABSTRACT: Due to severe contemporary energy issues, generating C₂₊ products from electrochemical carbon dioxide reduction reactions (eCO₂ RRs) gains much interest. It is known that the catalyst morphology and active surface structures are critical for product distributions and current densities. Herein, a synthetic protocol of nanoparticle morphology on copper metal-organic frameworks (n-Cu MOFs) is developed by adjusting growth kinetics with termination ligands. Nanoscale copper oxide aggregates composed of small particulates are yielded via calcining the Cu-MOF nanoparticles at a specific temperature. The resulting nanosized MOF-derived catalyst (n-MDC) exhibits Faradaic efficiencies toward ethylene and C₂₊ products of 63% and 81% at -1.01 V versus reversible hydro
