Abstract


The g-C3N4/TCPP porphyrin composite was successfully fabricated via self-assembly approach. The composite was characterized using UV-Vis spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and FT-IR techniques. The results showed good integration of the porphyrin nanofibers with diameter of less than 100 nm and the length of several micrometer on the g-C3N4’s surface. The prepared g-C3N4/TCPP porphyrin composite showed high photocatalytic efficiency for MB degradation under sunlight irradiation, with MB removal efficiency > 90% after 100 min of simulated sunlight irrdadiation. The g-C3N4/TCPP porphyrin composite could be used as a promising photocatalyst for the treatment of other organic dyes in water.
