The　self-restacking　of　graphene　nanosheets　inevitably　compromises　the　electrochemical　performance　of　conventional　graphene-based　materials.　Herein,　to　solve　this　problem,　we　prepared　a　new　type　of　three-dimensional　porous　aerogel　with　partially　unzipped　multiwalled　carbon　nanotubes　inserted　into　graphene　nanosheets　via　a　reduction-reaction-induced　self-assembly　process.　In　the　resulting　aerogels,　the　inner　carbon　nanotubes　(CNTs)　tightly　attach　to　the　unzipped　outer　graphene　nanoribbons　(GNRs),　which　bridge　with　the　graphene　nanosheets.　These　interconnections　bring　them　excellent　electrical　contact;　the　CNTs　act　as　spacers　to　prevent　the　restacking　of　adjacent　graphene　nanosheets,　and　the　abundant　interconnected　pores　in　the　aerogels　provide　large　channels　for　charge　transfer.　Accordingly,　the　aerogels　exhibit　a　specific　capacitance　of　348.4　Fg(-1)　at　a　scan　rate　of　5　mVs(-1),　with　capacitance　retention　remaining　at　89.7%　at　a　current　density　of　2　Ag-1　after　5000　cycles.　The　results　show　that　the　aerogels　are　promising　electrode　materials　for　supercapacitor　applications.
