Antimonene　(Sb)　has　been　widely　studied　owing　to　its　high　carrier　mobility,　high　thermal　conductivity,　and　tunable　electronic　properties.　Conventional　synthetic　methods　for　antimonene　nanosheets　(Sb-NSs)　are　more　complex　and　multi-step　reactions,　mainly　including　the　epitaxial　growth　method,　mechanical　peeling　method,　electrochemical　separation　method,　and　liquid-phase　separation　method.　Here,　we　report　a　simple　method　for　the　synthesis　of　Sb-NSs　on　Ni　foam　from　two-dimensional　(2D)　nanosheets　to　one-dimensional　(1D)　nanowires　via　hydrothermal　method.　The　fabricated　hexagonal　Sb-NSs　exhibit　a　transverse　scale　of　400　nm　and　a　thickness　of　approximately　50　nm.　When　evaluated　as　anode　materials　for　lithium　storage,　hexagonal　Sb-NSs　deliver　a　high　reversible　capacity　of　870.3　mAh　g-1　at　0.2　A　g-1　and　a　reversible　capacity　of　375　mAh　g-1　at　0.2　A　g-1　after　60　cycles.　As　a　result,　the　successful　preparation　of　dimensional-switching　Sb-NMs　provides　a　new　class　of　2D　materials　for　LIBs.　　©　2023　The　Author(s).　Published　by　IOP　Publishing　Ltd.
