Carbon　nitride　has　attracted　significant　interest　as　robust,　low-cost　alternative　to　metal-based　materials　in　fields　such　as　photo,　electro　and　heterogeneous　catalysis.　However,　the　properties　of　the　final　material　are　hard　to　control　by　traditional　synthetic　methods　Herein,　we　introduce　a　new　strategy　of　material　design　that　allows　controlling　the　desired　properties　of　the　final　material　already　from　the　molecular　level　by　sequential　solvent　treatment　of　supramolecular　aggregates　that　serve　as　the　reactants.　Due　to　in　situ　formation　of　a　thermodynamic　driven　energy　levels　gradient,　the　as-prepared　carbon　nitride　exhibits　almost　10　times　higher　activity　than　the　traditional　carbon　nitride　(calcined　from　melamine)　in　the　hydrogen　evolution　text.　As　a　multifunctional　catalyst,　the　core-shell　like　carbon　nitride　also　shows　a　superior　catalytic　degradation　activity　for　RhB　and　p-nitrophenol.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
