Metal organic frameworks (MOFs) have a porous structure, high surface area, and high charge transfer, and they have been regarded as model electrocatalysts. Optimization of the electrocatalytic activity of MOFs is challenging, and an effective strategy for this optimization is the construction of a well-defined interfacial bond bridge. In this work, an approach of composite synthesis is reported for MOF (CoNiNHBDC) with MXenes (MoTiC), as the electrocatalytic properties of MOF can be greatly enhanced with the incorporation of the conductive material MXene.
