Abstract In this work, Metaplexis japonica was used as raw material to prepare porous biomass carbon (AMJ) using KOH as activator. A facile two-step method is developed for growth of NiCo2S4 nanoparticles on AMJ, involving the growth of Ni-Co precursor by hydrothermal approach and subsequent conversion into NiCo2S4 nanoparticles through sulfidation process. The microstructure and morphologies of the resulting materials were characterized by XRD, SEM and N2 adsorption desorption analysis. The specific surface area of porous biomass carbon materials with tubular structure was 2831 m2/g, which was beneficial to charge accumulation between the electrolyte/electrode interfaces, and promote the diffusion and transport of electrolyte ions. Compared with pure NiCo2S4, the AMJ/NiCo2S4 electrode exhibited high specific capacitance of 1041.6 F/g at 5 mV/s, excellent rate capability and outstanding cycling stability.
