The MIL-88/PVB nanofibers were prepared by hydrothermal synthesis and subsequent electrostatic spinning. The composite was used as a high efficiency heterogeneous catalyst for photocatalysis coupling of Fenton process to remove tetracycline hydrochloride (TC-HCl) under visible light irradiation. The results indicated that 99% of TC-HCl (500mg·L^-1) was degraded in 90 min. The MIL-88/PVB nanofibers were easy to separate from solution. The results of scavenging experiments and ESR analysis demonstrated that •OH and •O^2- were the predominant radicals for the TC-HCl degradation. Moreover, the possible mechanism for enhanced degradation performance of TC-HCl in the heterogeneous catalytic oxidation system was proposed.

MIL-88 / PVB纳米纤维是通过水热合成和随后的静电纺丝制备的。该复合材料被用作高效多相催化剂，用于Fenton工艺的光催化偶合，以在可见光照射下去除盐酸四环素（TC-HCl）。结果表明，在90分钟内降解了99％的TC-HCl（500mg·L ^-1）。MIL-88 / PVB纳米纤维易于从溶液中分离。清除实验和ESR分析的结果表明，•OH和•O ^2-是TC-HCl降解的主要自由基。此外，提出了提高多相催化氧化体系中TC-HCl降解性能的可能机理。
