Abstract

Hierarchical Cu dendrites fabricated via Cl-mediated electrodeposition afford high C₂H₄ efficiency (58% faradaic efficiency at −0.9 V vs. RHE) for CO₂ electroreduction thanks to not only the optimal hydrophobicity/aerophilicity, but also the dominant distribution of active (100) and (110) facets.
