Facile preparation of carbon nitride by binary eutectic KNO₃/KCl molten salt and its photocatalytic performance evaluation.

ABSTRACT: Graphitic carbon nitride (g-C₃N₄) has been widely investigated and applied in photocatalysis, but it always suffers from unsatisfactory photocatalytic activity performance. In this study, a facile molten salt-assisted heat-treated g-C₃N₄via binary eutectic KNO₃/KCl was successfully developed. Based on this assumption, the heat treatment temperature has been successfully lowered to 350 °C to modulate and optimize the carbon nitride structure. The obtained target photocatalysts were characterized using various characterization methods (scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), Fourier transform infrared spe
