Synthesis of MIL-53(Fe)/MWCNTs Hybrid Material with Enhanced Efficiency for Photocatalytic Degradation of Rhodamine B

摘要

BMIL-53(Fe)/MWCNTs hybrid material was prepared via the solvethermal synthesis method. The resulting samples were characterized by X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy, UV-Vis absorption spectroscopy,the Brunauer–Emmet–Teller method, and photoluminescence spectroscopy. The result showed that the introduction of multiwalled carbon nanotubes to the MIL-53(Fe) can increase the surface area of the composites, suppress the recombination of photogenerated electron-hole pairs and promote the electron transfer process. The hybrid material showed optimal photocatalytic performance in the degradation of Rhodamine B under the irradiation of ultraviolet and natural light.
