Schematic diagram of Preparation and Enhanced Visible-light Photocatalytic by the decrease of RhB by different photocatalysts as a function of visible light irradiation time (photocatalysts loading, 0.5 g/L; initial RhB concentration, about 10 mg/L, without pH modulation). The photocatalysts used were pure g-C3N4 and a series of g-C3N4/ BiOCl hybrids, b cyclic degradation of RhB over BC3, c XRD patterns of BC3 photocatalysts before and after the photocatalytic process, and d plots of TOC versus degradation time.
