N2 - Ni3Fe(OH)80.5CO3·xH2O layered double hydroxide (NiFe-LDH) was used as a precursor to synthesize AgCl-BiOCl-NiFe-LDH composites to extend the light absorption of BiOCl in the visible light region. The synthetic AgCl-BiOCl-NiFe-LDH composites were characterized by XRD, FT-IR and UV-vis Diffuse Reflectance spectroscopy and FE-SEM. The photo-catalytic activity of AgCl-BiOCl-NiFe-LDH composites was evaluated for the decolorization of RhB under the visible light irradiation, which showed that 97.8% of the dye was degraded in 60 min. The photo-catalytic degradation of RhB by AgCl-BiOCl-NiFe-LDH was compared with those by BiOCl-NiFe-LDH and pure BiOCl but the latter two showed lower degradation than the former, which showed the highest activity among the investigated composites. Recycling experiments revealed that AgCl-BiOCl-NiFe-LDH kept very high activity after 4 cycles with an efficiency of 88.6%, which makes it a good candidate for visible-light responsive photo-catalyst with long-term usability.
