Metal–Organic Frameworks as Electrocatalysts

Angewandte Chemie International Edition, 2023
AbstractTransition metal complexes are well‐known homogeneous electrocatalysts. In this regard, metal–organic frameworks (MOFs) can be considered as an ensemble of transition metal complexes ordered in a periodic arrangement. In addition, MOFs have several additional positive structural features that make them suitable for electrocatalysis, including ...
