An Angstrom-Level D-Spacing Controlling Synthetic Route For Mos2 Towards Stable Intercalation Of Sodium Ions

In this paper, we precisely controlled the d-spacing of vertically aligned MoS2 arrays ranging from 6.2 to 10 angstrom via heating-controlled deintercalation of NH4+ ions. The finely controllable interlayer nanoarchitecture resulted in an optimal d-spacing of 7.3 angstrom, which on nitrogenous reduced graphene oxide (N-RGO) delivered a reversible capacity of 295 mA h g(-1) after 2000 cycles at 1 A g(-1) for Na+ intercalation.
