Abstract

A convenient template free method to prepare mesoporous g-C3N4 with a tunable band structure was reported by copolycondensation of dicyandiamide and urea. X-ray diffraction, N2 adsorption, elemental analysis, UV-visible spectroscopy, photoluminescence and X-ray photoelectron spectroscopy were used to characterize the prepared catalysts. The results indicated that copolycondensation of dicyandiamide and urea strongly influenced the polycondensation degree of prepared mesoporous g-C3N4 materials, leading to the difference in structural property, optimal property and electronic structure. The activities of prepared catalysts were tested in the photocatalytic degradation of Rhodamine B under visible light. The mass fraction of urea plays the important role on the photocatalytic performance. The possible mechanism was proposed.
