The electrical double-layer capacitor of NS-G acts as a supporting host for the growth of pseudocapacitance NCS nanoparticles, thus enhancing the synergistic electrochemical performance. The specific capacitance values of 1420.2 F g^-1 at 10 mV s^-1 and 630.6 F g^-1 at 1 A g^-1 are achieved with an impressive capability rate of 76.6% preservation at 10 A g^-1. Furthermore, the integrating NiCo₂S₄ nanoparticles embedding onto the NS-G surface also present a surprising improvement in the cycle performance, maintaining 110% retention after 10 000 cycles. Owing to the unique morphology an impressive energy density of 19.35 W h kg^-1 at a power density of 235.0 W kg^-1 suggests its potential application in high-performance supercapacitors.RSC advances<i>In situ</i> hydrothermal synthesis of nickel cobalt sulfide nanoparticles embedded on nitrogen and sulfur dual doped graphene for a high performance supercapacitor electrode.PMC9036894The 90th Anniversary of Chulalongkorn University (Ratchadaphisek somphot Endowment Fund)Pattananuwat PPotiyaraj PPoompiew Nfalse<i>In situ</i> hydrothermal synthesis of nickel cobalt sulfide nanoparticles embedded on nitrogen and sulfur dual doped graphene for a high performance supercapacitor electrode.Nickel cobalt sulfide nanoparticles (NCS) embedded onto a nitrogen and sulfur dual doped graphene (NS-G) surface are successfully synthesized <i>via</i> a two-step facile hydrothermal process.
