Abstract
AbstractModification of graphitic carbon nitride (g‐C3N4) photocatalyst with transition metals was achieved with a simple soft‐chemical approach using dicyandiamide monomer and metal chloride as precursors, in combination with a thermal‐induced polycondensation at 600 °C under nitrogen atmosphere. The resultant organic–inorganic hybrid materials were thoroughly characterized by a variety of techniques, including X‐ray diffraction (XRD), UV/Vis spectroscopy, X‐ray photoelectron spectroscopy (XPS), N2‐sorption, transmission electron microscopy (TEM), photoluminescence (PL), and FTIR. Benzene hydroxylation and styrene epoxidation reactions were employed to evaluate the catalytic/photocatalytic activity of the synthesized g‐C3N4‐based catalysts. Results showed that Fe‐ and Cu‐modified g‐C3N4 were active for the hydroxylation of benzene to phenol using H2O2 under mild conditions. It was also found that g‐C3N4 could promote the catalytic epoxidation of styrene using molecular oxygen as the primary oxidant; after modification with Co and Fe, the catalytic performance for styrene epoxidation with O2 could be significantly improved, especially when coupled with visible‐light irradiation.
