In this paper, we precisely controlled the d-spacing of vertically aligned MoS2 arrays ranging from 6.2 to 10 Å via heating-controlled deintercalation of NH4 + ions. The finely controllable interlayer nanoarchitecture resulted in an optimal d-spacing of 7.3 Å, 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.
