Unilamellar metallic nanosheets possess superiority for electrochemical energy storage and conversion applications compared to the few-layered bulk and semiconducting counterparts. Here, we report the utilization of unilamellar metallic IT phase MoS2 nanosheets for efficient sodium storage and hydrogen evolution through a MoS2/graphene superlattice. The superlattice-like assembly composed of alternately restacked unilamellar MoS2 and modified reduced graphene oxide nanosheets was prepared by a facile solution-phase direct restacking method. As an anode for sodium storage, the MoS2/graphene superlattice anode exhibited an excellent rate capability of similar to 240 mA h g(-1) at 51.2 A g(-1) and a stable reversible capacity of similar to 380 mA h g(-1) after 1000 cycles at 10 A g(-1). In addition, a low onset potential of similar to 88 mV and a small slope of 48.7 mV decade(-1) were attained for the hydrogen evolution reaction. Our findings are important for further developing the potential of 2D nanosheets for energy storage and conversion.
