Abstract

NiMoO 4 nanoparticles and quantum dots were uniformly distributed on the surface of reduced nanohole graphene oxide (rNHGO). NiMoO 4 @rNHGO exhibited a higher specific capacitance and better cycling stability than NiMoO 4 @reduced graphene oxide (rGO), which were attributed to the large surface area and high electrical conductivity. NiMoO 4 nanoparticles and quantum dots (QDs) had high surface to volume ratio, which would not result in change in volume during the electro–chemical operation and induced better supercapacitor performance. Moreover, synergistic effect between NiMoO 4 and the rNHGO also improved undoubtedly high specific capacitance and cycle stability.
