abstract = {The development of effective and precious‐metal‐free
electrocatalysts for the oxygen evolution reaction (OER)
represents a major bottleneck to unlock a renewable energy
scenario based on water splitting technologies. Materials
uniting the electrical conductivity of conjugated graphitic
nanomaterials with the chemical regularity of
metal‐organic‐framework (MOF) crystals are promising
precursors for such electrocatalysts. Nanoscale integration
of these two materials is challenging. A new synthesis route
is developed that integrates 2D MOF nanocrystals and
graphitic carbon nanolamellae into layered composites. The
graphitic carrier contributes excellent charge–transport
properties, and the 2D macromolecular MOF precursor provides
a suitable shuttle for introducing highly dispersed metal
species. Furthermore their direct chemical environment can
be controlled via selection of organic linker. Thermal
decomposition of 2D cobalt tetrafluoro
benzene‐dicarboxylate MOF nanocrystals within such
composites enables the stabilization of cobalt
oxyhydroxyfluoride nanoparticles on the graphitic carrier,
which display an extraordinary activity for the OER in
alkaline media, with low onset overpotential (310 mVRHE) and
current densities >104 mA cm−2 μmolCo−1 at an operating
overpotential of 450 mV, alongside excellent operational
stability. The wide compositional array of MOFs makes this
synthesis approach versatile toward advanced
(electro)catalysts and other functional materials for
applications from sensing to energy storage and conversion.},
