中文摘要:
      利用表面活性剂能够控制所制备的金属有机骨架材料MIL-53(Fe)的孔道开孔方式。表面活性剂四乙基氢氧化铵(TEAOH)能够控制MIL-53(Fe)的孔道开孔方式为闭孔结构。而表面活性剂聚氧乙烯-聚氧丙烯-聚氧乙烯(P123)和聚乙烯醇(PVA)能够控制MIL-53(Fe)的孔道开孔方式为开放孔结构。通过在紫外光照射下催化降解染料罗丹明B的实验来检测不同孔道开放程度对MIL-53(Fe)的光催化性能的影响。结果表明,开放孔的MIL-53(Fe)比闭孔的MIL-53(Fe)呈现出更强的光催化活性。具有最强催化活性的MIL-53(Fe)-PVA能够在90分钟之内降解100%的罗丹明B。
英文摘要:
      A new approach for dominating the channel form of the flexible MIL-53(Fe) was developed by using a surfactant-assisted modified method. The surfactant tetraethylammonium hydroxide (TEAOH) can control the channel form of MIL-53(Fe) for 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)-PVA that exhibit the best photocatalytic activity degraded almost 100% Rh B in 90 minutes.
