Ferrocene　moieties　were　heterogenized　onto　carbon　nitride　polymers　by　a　covalent　CN　linkage　bridging　the　two　conjugation　systems,　enabling　the　merging　of　the　redox　function　of　ferrocene　with　carbon　nitride　photocatalysis　to　construct　a　heterogeneous　Photo-Fenton　system　for　green　organocatalysis　at　neutral　conditions.　The　synergistic　donor-acceptor　interaction　between　the　carbon　nitride　matrix　and　ferrocene　group,　improved　exciton　splitting,　and　coupled　photocatalytic　performance　allowed　the　direct　synthesis　of　phenol　from　benzene　in　the　presence　of　H2O2　under　visible　light　irradiation.　This　innovative　modification　method　will　offer　an　avenue　to　construct　functionalized　two-dimensional　polymers　useful　also　for　other　green　synthesis　processes　using　solar　irradiation.
