Fe-g-C3N4-LUS-1was prepared by the thermal decomposition of dicyandiamide inside the pores of LUS-1under an inert atmosphere.It was used as a photocatalyst for the hydroxylation of benzene to phenol in sunlight.The catalysts were characterized by Fourier transform infrared spectroscopy,N2 adsorption-desorption,X-ray diffraction,and scanning electron microscopy.In Fe-g-C3N4-LUS-1,a single layer of graphitic carbon nitride (g-C3N4) was formed on the surface of LUS-1.The photocatalytic activity of the iron containing g-C3N4based catalysts was investigated,and the catalytic activity was remarkably enhanced when the reaction condition was changed from dark to sunlight.The best result was obtained with 20％Fe-g-C3N4-LUS-1 in sunlight.
