1T-phase　molybdenum　disulfide　(1T　MoS2)　can　efficiently　facilitate　the　charge　transfer　and　provide　the　active　site,　exhibiting　a　better　hydrogen　evolution　reaction　(HER)　than　2H　MoS2.　However,　its　thermodynamic　instability　becomes　a　major　drawback　that　hinders　its　practical　application.　We　report　a　chemical　vapor　deposition　(CVD)　method　to　grow　MoS2　nanosheets　with　high　1T　content　(61.5%)　by　introducing　an　appropriate　amount　of　antimony　oxide.　The　1T-2H　hybrid　structures　grown　in　this　mode　are　thermodynamically　stable.　1T　phase　of　the　MoS2　produces　a　unique　charge　distribution　that　makes　the　S　atoms　at　the　1T-2H　interface　more　favorable　for　H　adsorption,　thus　enhancing　the　HER　activity　on　the　MoS2　basal　plane.　This　study　has　provided　a　new　idea　for　the　1T-phase　MoS2　preparation　for　efficient　HER.　©　2023　Elsevier　B.V.
