Bimetallic MOF-Derived FeCo-P/C Nanocomposites as Efficient Catalysts for Oxygen Evolution Reaction

Oxygen evolution reaction (OER) demands cost-effective electrocatalysts with high catalytic performance. In this effort, metal-organic framework (MOF)-derived nanocomposites are presenting promising prospects to achieve this goal. Herein, Fe-Co bimetallic MOFs with different compositions are prepared through a sodium hydroxide assisted approach. By means of a successive carbonization and phosphating reaction, a series of MOF-derived multicomponent products are synthesized. The resultant P-doped products present enhance electrocatalytic performance for OER in alkaline electrolyte in comparison with a commercial RuO2 catalyst, which paves the way for their practical applications for water splitting. The developed method herein also offers an opportunity for the large-scale preparation of MOF-derived product toward energy conversion applications.
