In　this　minireview,　advances　in　the　applications　of　graphene　(GR)-based　composite　photocatalysts　for　selective　organic　synthesis　have　been　summed　up　systematically.　GR,　with　unique　planar　structure,　excellent　transparency,　superior　electron　conductivity,　high　specific　surface　area　and　high　chemical　stability,　is　proven　to　be　a　promising　component　to　construct　effective　GR-based　composite　photocatalysts　for　organic　transformations,　including　selective　oxidation　of　alcohols,　epoxidation　of　alkenes,　hydroxylation　of　phenol,　and　reduction　of　carbon　dioxide　(CO2).　In　addition　to　the　well-known　role　of　GR　as　a　photoelectron　reservoir,　the　novel　functions　of　GR　as　an　organic　dye-like　macromolecular　photosensitizer　and　graphene　oxide　(GO)　itself　as　a　photocatalyst　for　selective　synthesis　are　also　presented.
