The　electrical　conductivity　and　charge　carrier　mobility　of　reduced　graphene　oxide　(RGO)　based　3D　aerogel　using　graphene　oxide　(GO)　as　precursor　is　often　restricted　by　the　intrinsic　population　of　defects　and　thus　disruption　of　2D　π-conjugation　in　the　domain　of　RGO　sheets.　Here,　we　report　a　facile　and　efficient　approach　to　improve　the　electrical　conductivity　of　RGO　aerogel　by　introducing　highly　conductive　commercial　Elicarb　graphene　(EGR).　GO　acting　as　a　“macromolecular　surfactant”　can　be　used　to　simultaneously　resolve　the　intrinsic　drawback　of　low　solution　dispersibility　of　EGR　and　provides　the　basic　skeleton　for　solution-processable　synthesis　of　RGO@EGR-Eosin　Y　(RGO@EGR-EY)　metal-free　3D　aerogel　composites.　The　as-synthesized　RGO@EGR-EY　aerogel　with　superior　electrical　conductivity　facilitates　more　efficient　separation　and　transfer　of　photogenerated　charge　carriers,　and　consequently　exhibits　much　higher　photocatalytic　activity　than　RGO-EY　aerogel.　It　is　hoped　that　our　current　work　could　open　promising　prospects　for　the　rational　utilization　of　highly　conductive　commercial　graphene　to　fabricate　graphene-based　aerogel　for　enhanced　photoredox　applications.　©　2017　Elsevier　B.V.
