摘要: The present work described the construction of a highly-efficient and stable adsorbent for removing hazardous pesticide from water. Water-stable metal-organic framework (MOF) nanosheets with three-dimensional (3D) structure, named as Al-TCPP nanosheets, were fabricated using aluminum (III) chloride hexahydrate and tetrakis (4-carboxyphenyl) porphyrin as the monomers with the assistance of a cetyltrimethylammonium bromide. Al-TCPP nanosheets and bulk crystals were comprehensively characterized to explore their differences in morphologies, microstructures and porous properties. Al-TCPP nanosheets kept the original crystal structure with an average thickness of similar to 17 nm. They also displayed excellent hydrophilic property, water stability and hierarchical porous structure with the surface area of 1359 m(2) g(-1), which were beneficial to the adsorption of chlorantraniliprole. Adsorption experiments were carried out and the maximum adsorption capacity of chlor-antraniliprole on Al-TCPP nanosheets achieved 371.91 mg g(-1), which was obviously higher than that of the bulk crystals (222.11 mg g(-1)). The disparity should be attributed to the hierarchical porous structures and highly exposed active sites of nanosheets. These results illuminate that MOF nanosheets can be a promising material for the adsorption of hazardous contaminants in water treatment.
