A　novel　heterogeneous　Fenton-like　photocatalyst,　Fe-doped　graphitic　carbon　nitride　(Fe-g-C3N4),　was　produced　by　facile　two-step　calcination　method.　This　Fe-g-C3N4　catalyzed　rhodamine　B　degradation　in　the　presence　of　H2O2　accompanied　with　visible　light　irradiation.　transmission　electron　microscopy(TEM),　x-ray　diffraction　(XRD),　FT-IR,　x-ray　photoelectron　spectroscopy　(XPS),　and　photoluminescence　fluorescent　spectrometer　(PL)　characterization　analysis　methods　were　adopted　to　evaluate　the　physicochemical　property　of　samples.　It　can　be　observed　that　the　Fe-g-C3N4　exhibited　excellent　photocatalytic　Fenton-like　activity　at　a　wide　pH　range　of　3-9,　with　rhodamine　B(RhB)　degradation　efficiency　up　to　95.5%　after　irradiation　for　45　min　in　the　presence　of　1.0　mM　H2O2.　Its　high　activity　was　ascribed　to　the　formation　of　Fe-N　ligands　in　the　triazine　rings　that　accelerated　electron　movement　driving　the　Fe(III)/Fe(II)　redox　cycle,　and　inhibited　photo-generated　electron　hole　re-combinations　for　continuous　generation　of　reactive　oxygen　species　by　reactions　between　Fe(II)　and　H2O2.　The　main　active　oxygen　species　were　hydroxyl　radicals,　followed　by　superoxide　radicals　and　hole　electrons.　This　produced　catalyst　of　Fe-g-C3N4　shows　excellent　reusability　and　stability,　and　can　be　a　promising　candidate　for　decontamination　of　wastewater.
