Mesoporous Copper-Based Metal-Organic Framework Flakes as a Promising Platform for Electrosynthesis of Ethylene from Carbon Dioxide. [PDF]

Small Sci
We report a one‐pot green synthesis of a flake‐like, mesoporous Cu‐based metal‐organic framework for CO2 conversion. Its structure enhances mass transport and active‐site accessibility, promoting C–C coupling. In a zero‐gap cell, it achieves 51.6% C2H4 selectivity at 200 mA cm–2.
