Cu2O/reduced　graphene　oxide　(RGO)　composite　aerogel　was　fabricated　by　a　one-pot　hydrothermal　method　using　glucose　as　a　reducing　agent　and　cross-linker.　The　as-obtained　Cu2O/RGO　composite　aerogel　showed　superior　photocatalytic　activity　for　MO　degradation　owing　to　its　improved　light　absorption　capability,　enhanced　adsorption　toward　pollutant　and　the　RGO　promoted　charge　carrier　separation.　The　Cu2O/RGO　composite　aerogel　can　also　be　facilely　separated　from　the　reaction　system　for　recycling,　which　makes　it　especially　appealing　for　using　as　a　visible　light　responsive　photocatalyst　in　aqueous　photocatalysis.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
