Herein, Fe is loaded into g-C3N4 nanosheets (Fe@g-C3N4) to form a photoactive system for H2 evolution. The loaded Fe species are present in the +3 oxidation state in the form of amorphous clusters. Upon loading 0.4 atomic% of Fe into g-C3N4, the H2 evolution rate under visible light increases from 2.19 μmol/g h (g-C3N4) to 17.39 μmol/g h (0.4Fe@g-C3N4). Meanwhile, the population of photoexcited electrons increases by 10.6 times in 0.4Fe@g-C3N4. The improved separation of electron-hole is behind the enhanced photoactivity for H2 evolution with Fe@g-C3N4.
