Iron-Cluster-Directed Synthesis of 2D/2D Fe–N–C/MXene Superlattice-like Heterostructure with Enhanced Oxygen Reduction Electrocatalysis

Metal clusters, an emerging category of materials with molecular metal dispersity, have been proposed for versatile applications. In this work, we show an unexpected function of metal clusters, which can contribute to preparing 2D/2D superlattice-like heterostructures. The key step is to use metal clusters to adjust the surface charge of 2D nanosheets and, consequently, match the charge negativities per surface area for different 2D nanosheets,...
