Heterostructured materials with single metal-atom dispersion are desirable for hydrogen production. However, it remains a great challenge to achieve large-scale fabrication of single atom-anchored heterostructured catalysts with high stability, low cost, and convenience. Here, we report single iron (Fe) atom-dispersed heterostructured Mo-based nanosheets developed from a mineral hydrogel. These rationally designed nanosheets exhibit excellent hydrogen evolution reaction (HER) activity and reliability in alkaline condition, manifesting an overpotential of 38.5 mV at 10 mA cm^-2, and superior stability without performance deterioration over 600 h at current density up to 200 mA cm^-2, superior to most previouslyNature communicationsTwo-dimensional mineral hydrogel-derived single atoms-anchored heterostructures for ultrastable hydrogen evolution.PMC9586971GXWD20201230155427003-202008241052360012022A15150114022017YFA0204403ZDSYS202106161100000012020A1515110236Sun LZeng SPan JBu YBao YMa FXLu JLyu FCheng LLi YYJia ZMao ZfalseTwo-dimensional mineral hydrogel-derived single atoms-anchored heterostructures for ultrastable hydrogen evolution.Hydrogen energy is critical for achieving carbon neutrality.
