摘要: 提出了一种利用表面活性剂控制柔性金属有机骨架材料MIL-53(Fe)孔道结构的方法。表面活性剂四乙基氢氧化铵(TEAOH)控制MIL-53(Fe)的孔道形式为“闭孔”的形式,而表面活性剂聚环氧乙烷-聚环氧丙烷-聚环氧乙烷(P123)或者聚乙烯醇(PVA)控制MIL-53(Fe)的孔道形式为“开孔”的形式。通过紫外光辐射降解罗丹明B水溶液的方式来考察不同孔道形式的MIL-53(Fe)的光催化性能。结果表明“开孔”的MIL-53(Fe)比“闭孔”的MIL-53(Fe)呈现出更高的光催化活性。由表面活性剂PVA改良的MIL-53(Fe)具有最好的光催化活性,90分钟内讲解了100%的罗丹明B水溶液。

Abstract: An approach for dominating the channel form of the flexible MIL-53(Fe) was developed by using a surfactantassisted modified method. The surfactant tetraethylammonium hydroxide (TEAOH) can control the channel form of MIL- 53(Fe) to be a “closed-pore” form, whereas the surfactant polyoxyethylene polyoxypropylene polyoxyethylene (P123) or polyvinyl alcohol (PVA) can dominate the channel form of MIL-53(Fe) for a “large-pore” form. The photocatalytic performance of MIL-53(Fe) with different channel forms was investigated through the degradation of rhodamine B (Rh B) in water under violet light irradiation. The results showed that MIL-53(Fe) with a “large-pore” form exhibited higher photocatalytic activity than that of MIL-53(Fe) with a “closed-pore” form. MIL-53(Fe) modified with PVA exhibit the best photocatalytic activity degraded almost 100% Rh B in 90 minutes.
