Facile preparation of KBiO₃/g‐C₃N₄ composites with microwave irradiation for photocatalytic hydrogen production

BACKGROUND KBiO 3 /g‐C 3 N 4 composites were prepared under microwave irradiation to different weight ratios of KBiO 3 (5, 10, 20, 30, 40, 50, 60, 70 80, 90%wt) using a Mars‐6 microwave for 30 min at 100 W. The samples were characterized by X‐ray diffraction (XRD), Fourier transform infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS)‐ mapping, N 2 physisorption and diffuse reflection...
