The　future　energy　crisis　and　environmental　degradation　can　only　mitigate　by　harvesting　solar　energy　into　renewable,　safe,　economical　and　clean　technology　like　water　splitting.　The　graphitic　carbon　nitride　has　an　attractive　band　structure,　good　chemical　stability,　earth-abundant　and　significantly　easily　fabricated　which　makes　an　application　for　the　generation　of　hydrogen　by　water　splitting.　In　this　paper,　we　try　to　critically　focus　on　the　current　progress　and　future　development　of　the　different　strategies　of　water　splitting　using　graphitic　carbon　nitride　(g-C3N4)　for　hydrogen　generation.　In　this　context,　we　discuss　recent　strategies　like　metal　and　non-metal　doping　(electronic　structure),　morphology　tuning　(geometric　structuring),　use　of　mediators　(Z-scheme　technology),　defects　engineering,　plasmonic　materials,　dye-sensitization,　perovskite　oxides,　carbon　nitrides,　carbon　dots,　metal　organic　framework,　and　a　bimetallic　cocatalyst.　Finally,　we　summarize　the　recent　advances　and　future　developments　of　g-C3N4　bases　photocatalysis.
