The　molybdenum　disulfide　(MoS2)　and　the　graphene　aerogel　(GA)　were　hybridized　into　a　porous　three-dimensional　network　composite　(MoS2/GA).　Due　to　its　large　specific　surface　area,　good　electrical　conductivity　and　stable　structure,　MoS2/GA　has　higher　discharge　specific　capacity　and　better　rate　performance　than　MoS2　and　MoS2/GNRs　as　electrode　materials.　Moreover,　MoS2/GA　has　better　hydrogen　evolution　catalytic　activity　and　durability.　Graphic　A　porous　three-dimensional　network　can　be　built　in　MoS2/GA　composites.　Hybridization　gives　MoS2　nanosheets　wider　interlayer　spacing,　fewer　layers,　larger　BET　surface　area,　and　more　active　sites.　It　can　be　found　that　MoS2/GA(100:15)　is　the　efficient　HER　electrocatalytic　material　and　the　energy　storage　material　than　MoS2　and　MoS2/GNR　due　to　the　superior　electrocatalytic　activity　and　durability.　[GRAPHICS]　.
