Graphitic　carbon/carbon　nitride　hybrid　was　fabricated　by　a　two-step　procedure　from　the　initially　hydrothermal　self-assembly　of　melamine　and　sucrose　and　then　typical　thermal　condensation.　The　structure,　composition,　photoelectric　and　photocatalytic　properties　of　the　resulting　sample　was　characterized　in　detail　by　X-ray　diffraction,　Fourier　transform　infrared　spectra,　Raman　spectra,　X-ray　photoelectron　spectroscopy,　transmission　electron　microscopy,　UV-vis　diffuse　reflectance　spectroscopy,　photoelectric　current,　electrochemical　impedance　spectroscopy　and　photocatalytic　hydrogen　production.　The　results　revealed　that　the　graphitic　carbon/carbon　nitride　hybrid　has　conjugation　effect　between　carbon　nitride　and　graphitic　carbon　and　thus　leads　to　a　better　efficiency　for　water　splitting　than　the　pristine　carbon　nitride.
