Crystalline　graphitic　carbon　nitride　is　an　excellent　photocatalyst　for　hydrogen　production　due　to　its　non-toxicity,　stability,　elemental　abundance,　and　visible-light　response.　Herein,　we　present　a　new　type　of　composite　photocatalysts,　eco-friendly　bamboo-charcoal-loaded　graphitic　carbon　nitrides　to　accelerate　the　separation　of　electron-hole　pairs.　The　suitable　loading　of　bamboo　charcoal　on　graphitic　carbon　nitrides　shows　an　increased　specific　surface　area　from　85　to　120　m2　g−1,　and　excellent　visible-light　photocatalytic　hydrogen　production　activity　of　4.1　mmol　g−1　h−1,　which　is　2.3　times　higher　than　that　of　pristine　carbon　nitride　(1.8　mmol　g−1　h−1).　Under　irradiation,　the　photogenerated　electrons　fast　migrate　from　graphitic　carbon　nitride　to　bamboo　charcoal　through　an　ohmic　contact　between　them,　reducing　the　recombination　of　electron-hole　pairs.　This　study　highlights　the　effect　of　carbonaceous　material　loading　on　photocatalytic　activity　of　carbon　nitrides　and　opens　an　avenue　to　design　efficient　loaded　photocatalysts　with　natural　abundant　materials.　©　2021　The　Author(s)
