摘要：
The visible-light responsive photocatalyst of g-C3N4@BiOCl with hollow flower-like structure was fabricated via self-assembly strategy. The as-prepared heterojunction photocatalyst was characterized by X-ray diffraction, scanning electron microscopy, high-resolution transmission microscopy, energy dispersive X-ray spectroscopy, ultraviolet-visible diffuse reflection spectra and X-ray photoelectron spectroscopy. Due to the excellent ability of charge separation, the heterojunction photocatalyst exhibited much higher photocatalytic activity than g-C3N4 and BiOCl. The degradation efficiency of 50 mg.L-1 rhodamine B can be reached to 99% within 12 min under visible-light irradiation (lambda >= 420 nm).
