A　BiOBr/reduced　graphene　oxide　(RGO)　composite　aerogel　with　BiOBr　nanoplates　grown　on　an　interconnected　three-dimensional　RGO-based　porous　network　was　prepared　by　one-pot　hydrothermal　method　using　L-lysine　as　a　reducing　agent　and　the　cross-linker.　Its　enhanced　adsorption　toward　pollutants　owing　to　its　large　Brunauer-Emmett-Teller　specific　surface　area　and　spongy　nature,　improved　light　absorption　due　to　its　extremely　lightweight　nature　and　the　RGO　promoting　photogenerated　charge　separation　contributed　to　the　BiOBr/RGO　aerogel＇s　enhanced　activity　for　photocatalytic　degradation　in　an　aqueous　system.　The　BiOBr/RGO　aerogel　also　showed　high　stability　and　can　be　easily　separated　from　the　reaction　systems　for　recycling.　The　facile　one-pot　method　has　been　proved　to　be　generic　in　the　formations　of　different　semiconductor　embedded　RGO　aerogels　like　BiOX/RGO　(X　=　Cl　and　I),　CdS/RGO　and　Fe2O3/RGO　aerogels,　which　combine　the　advantages　of　enhanced　photocatalytic　activity　with　facile　recycling　for　applications　in　aqueous　photocatalytic　reaction　systems.
