Boosting Electrochemical CO 2 Reduction on Metal–Organic Frameworks via Ligand Doping
Abstract Electrochemical CO 2 reduction relies on the availability of highly efficient and selective catalysts. Herein, we report a general strategy to boost the activity of metal–organic frameworks (MOFs) towards CO 2 reduction via ligand doping. A strong electron‐donating molecule of 1,10‐phenanth...
