摘      要：A novel carbon-rich g-C_(3)N_(4) nanosheets with large surface area was prepared by facile thermal polymerization method using urea and 1,3,*** of carbon-rich functional groups were introduced into the surface layers of g-C_(3)N_(4),which constructed the built-in electric field(BIEF)and resulted in improved charge separation;therefore,the carbon-rich g-C_(3)N_(4) displayed superior photocatalytic activity for amoxicillin degradation under solar *** contaminant degradation mechanism was proposed based on radical quenching experiments,intermediates analysis and density functional theory(DFT)***,the reusing experiments showed the high stability of the material,and the amoxicillin degradation under various water matrix parameters indicated its high applicability on pollutants treatment,all of which demonstrated its high engineering application potentials.
