| 1 | Morphology selective construction of β-cyclodextrin functionalized Fe3O4-Bi2WO6 nanocomposite with superior adsorptivity and visible-light-driven catalytic activity显示文摘Controlled growth of Bi2WO6 nanorods with exposed[001]facets and the fabrication of an Fe2O4-Bi2WO6 magnetic composite by a microwave-assisted polyol process,were achieved in this study.The adsorp-tivity and photocatalytic performance of the composite toward sunset yellow dye degradation were greatly enhanced by the β-cyclodextrin cavities on its surface,firmly anchored through a cetyltrimethylammonium bro-mide linkage.A series of examinations and characteriza-tions were carried out to determine the influence of various factors on the morphological modulation-photocatalytic behavior of the pure Bi2WO6 prior to final functionaliza-tion.Changing the pH of the precursor solution impacted the formation of 0D,2D,and 3D structures;however,the presence of hexamethylenetetramine surfactant induced the development of 1D nanorod structure.A reasonable crystal growth mechanism was proposed to elucidate the formation process.Conversely,the mechanism of the activity enhancement of β-cyclodextrin functionalized Fe2O4-Bi2WO6,compared to that of the non-functiona-lized samples,could be realized with the assistance of chemical trapping experiments on sunset yellow,and was confirmed on the colorless antibiotic(sulfamethoxazole).The high performance and durability of this composite can be attributed to the facet-dependent activity,large adsorp-tion capacity due to inclusion interactions,enhanced visible light absorption,and efficient charge separation. | Maher Darwish Ali Mohammadi Navid Assi Samer Abuzerr Youssef Alahmad | 2020 | Frontiers of Chemical Science and Engineering2020，14，4： | 1 |
