摘要

The remarkable potential of metal-organic frameworks (MOFs) has garnered significant attention, primarily attributed to their unique and adjustable structural characteristics, which hold promise for various applications, including electrocatalysis. Nevertheless, utilizing MOFs directly in oxygen electrocatalysis presents a formidable challenge due to the intricate control needed to modulate their size, composition, and morphology while ensuring an abundance of active sites. Here, we present a straightforward synthesis method that generates novel NiCoFe-based trimetallic MOF nanostructures. These structures demonstrate exceptional catalytic performance in the oxygen evolution reaction (OER) under alkaline conditions when employed as catalysts. Specifically, the FeNi2Co1-MOF exhibits the crucial overpotential of 143 mV required to attain a current density of 10 mA cm−2. Furthermore, it showcases a low Tafel slope of 68 mV dec−1 and maintains outstanding durability throughout extensive long-term testing.
