The Effect of Different g-C3N4 Precursor Nature on Its Structural Control and Photocatalytic Degradation Activity

Due to its good visible-light photocatalytic activity and environmental friendliness, g-C3N4 has attracted much attention. The relationship between precursor type the properties of obtained catalysts is interesting investigate. In this work, target were prepared via thermal polymerization different precursors, melamine, a mixture urea melamine cyanuric acid. characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometry (FT-IR), UV–vis diffuse reflectance spectroscopy (UV–vis DRS), scanning electron microscopy (SEM). Through characterization analysis, adjusting precursors could result in change microstructure. maximum BET surface area was 98.04 cm3g−1 through controlling, more than eight times that MCN (11.15 cm3g−1) using as precursor. decomposition process also analyzed discuss interaction with controlling. introduction acid led formation special nanotube structure additional function groups on increase activity.
