Graphene　(GR),　a　single-layer　carbon　sheet　with　a　hexagonal　packed　lattice　structure,　has　displayed　attractive　potential　and　demonstrably　become　the　research　focus　in　artificial　photocatalysis　due　to　its　enchanting　properties　in　enhancing　light　absorption,　electron　transfer　dynamics,　and　surface　reactions.　Currently,　numerous　efforts　have　shown　that　the　properties　of　GR,　which　are　closely　correlated　to　the　photocatalytic　performance　of　GR-based　composites　are　significantly　affected　by　the　synthesis　methods.　Herein,　we　first　introduce　the　optimization　strategies　of　GR-based　hybrids　and　then　elaborate　the　synthesis　of　GR-based　composite　photocatalysts　oriented　by　manifold　roles　of　GR　in　photoredox　catalysis,　containing　photoelectron　mediator　and　acceptor,　improving　adsorption　capacity,　regulating　light　absorption　range　and　intensity,　as　well　as　macromolecular　photosensitizer.　Beyond　that,　a　brief　outlook　on　the　challenges　in　this　burgeoning　research　field　and　potential　evolution　strategies　for　enhancing　the　photoactivity　of　GR-based　hybrids　is　presented　and　we　anticipate　that　this　review　could　provide　some　enlightenments　for　the　rational　construction　and　application　of　multifunctional　GR-based　composite　photocatalysts.　©　2022　Dalian　Institute　of　Chemical　Physics,　the　Chinese　Academy　of　Sciences
