The　thin　films,comprising　hierarchical　C-coated　MoS　2　(C@MoS　2　@C)　nanobelts,were　synthesized　by　continuous　hydrothermal-decomposition　with　reactants　of　Mo-powder,H　2　O　2　(30%),malic　acid　and　thiourea.The　microstructures　and　Li-ion　storage　behavior　of　the　C@MoS　2　@C　nanobelts　were　investigated　with　X-ray　diffraction,scanning　electron　microscopy,transmission　electron　microscopy　and　cyclic　voltammetry.The　results　show　that　the　C@MoS　2　@C　nanobelts　with　good　Li-ion　storage　capacity　can　be　synthesized　by　hydrothermal-decomposition.For　example,when　cycled　for　100　times　at　0.2　A/g　and　1.0　A/g,the　specific　capacity　of　the　rate-capacity　of　the　C@MoS　2　@C　nanobelts　was　1025.5　and　820　mAhg　-1　,respectively.The　C-coated　MoS　2　nanobelts　can　be　synthesized　by　hydrothermal-decomposition　decomposition　of　the　C-coated　MoO　3　-precursor;　while　keeping　the　nano-structures　intact,the　C-coating　is　capable　of　promoting　MoS　2　nano-sheets　formation　on　the　surface　of　C-template,significantly　increasing　the　MoS　2　-conductivity.The　as-synthesized　C@MoS　2　@C　films　possess　high　conductivity　and　structural　stability.　©　2018,　Journal　of　Vacuum　Science　and　Technology　Publishing　House.　All　right　reserved.
