Molybdenum　disulfide　(MoS2)　exhibits　large　layer　spacing　(0.62　nm)　and　considerable　theoretical　capacity　(670　mAh　g−1),　which　has　been　expected　to　be　used　as　anode　materials　for　sodium　ion　batteries　(SIBs).　However,　MoS2　prepared　by　traditional　hydrothermal　method　has　the　disadvantages　of　poor　conductivity,　easy　agglomeration　and　uncontrollable　morphology.　Therefore,　in　this　work　two　kinds　of　carbonaceous　materials　(carbon　nanotubes　and　nitrogen　doped　carbon)　are　used　to　improve　the　electrochemical　sodium　storage　ability　of　MoS2　at　the　molecular　level　and　micron　scale　by　one-pot　hydrothermal　method.　Among　them,　carbon　nanotubes　contribute　greatly　to　the　conductivity　and　morphology　of　the　composites　at　the　micron　scale,　while　cetyltrimethylammonium　bromide　(CTAB)　derived　nitrogen　doped　carbon　is　inserted　into　the　interlayer　of　MoS2　crystal　at　the　molecular　level　to　realize　the　layer　by　layer　protection　of　MoS2.　Meanwhile,　it　is　found　that　the　CTAB　addition　amount　of　1.5　mmol　for　the　optimized　experiment　can　provide　the　best　electrochemical　performance　of　the　final　modified　MoS2　electrode　materials.　Experiments　show　that　the　synergistic　dual-carbon　MoS2　composite　has　uniform　diameter　of　1　μm　flower　ball　morphology,　excellent　conductivity　and　improved　cycle　stability　along　with　a　high　capacity　of　350　mAh　g−1　at　1A　g−1　after　500　cycles,　showing　a　high　capacity　retention　rate　of　89.4%.　This　work　may　develop　a　simple　and　effective　way　to　synthesis　high　performance　two-dimensional　MoS2　composite　anode　for　SIBs.　©　2022　Elsevier　B.V.
