Hierarchically structured BiOCl/LDHs composites with well-developed porosity and high surface area have been prepared by an in situ growth of BiOCl on the surfaces LDHs fibers, and their adsorption capacities and photocatalytic activities are investigated by using methylene blue (MB) as model pollutants. The results indicate that the BiOCl/LDHs composites possess high surface area up to 126.2 m2/g. The as-prepared BiOCl/LDHs composites exhibited higher adsorptive ability and improved photocatalytic activity compared to bare BiOCl particles and LDHs fibers based on the removal of MB in aqueous solution, showing that BiOCl/LDHs composites can be used as efficient environmentally friendly materials for dye wastewater treatment.
