Electrocatalyst Support Durability

ECS Meeting Abstracts, 2014
While commercialization of PEFCs has been started in residential application and is planned in automotive application, detailed understanding of degradation phenomena is essential. A large part of PEFC degradation, especially in automotive applications, is known to be related to carbon support degradation, mainly caused by carbon corrosion and related ...

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 ...
