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.　(c)　2021　The　Author(s).　Published　by　Elsevier　Ltd　on　behalf　of　Hydrogen　Energy　Publications　LLC.　This　is　an　open　access　article　under　the　CC　BY　license　(http://creativecommons.org/　licenses/by/4.0/).
