Ferrocene is used as a catalytically active site and building block to construct a new conjugated microporous polymer (CMP), named Fc-POP. A corresponding carbon nanotube composite (CNTs@Fc-POP) with tubular structure was obtained through the π-π interaction between multi-walled carbon nanotubes (MWCNTs) and reactive molecules. This innovative modification method of carbon nanotubes provides a way to construct functionalized carbon materials. The two materials can achieve high conversion and selectivity of benzene hydroxylation to phenol under light irradiation using hydrogen peroxide (HO) as an oxidant. Due to the synergistic effect between the carbon nanotubes and the ferrocene group, the incorporation of MWCNTs can improve the yield of phenol significantly. This work explores a new photocatalystic system and expands the related photocatalytic application of CNTs.
二茂铁用作催化活性位点和构建单元，以构建一种名为Fc-POP的新型共轭微孔聚合物（CMP）。通过多壁碳纳米管（MWCNTs）与反应性分子之间的π-π相互作用，获得了具有管状结构的相应碳纳米管复合材料（CNTs@Fc-POP）。这种创新的碳纳米管改性方法为构建功能化碳材料提供了一条途径。这两种材料在以过氧化氢（HO）作为氧化剂的光照条件下，能够实现苯羟基化生成苯酚的高转化率和选择性。由于碳纳米管与二茂铁基团之间的协同效应，MWCNTs的引入可显著提高苯酚的产率。这项工作探索了一种新的光催化体系，并拓展了碳纳米管的相关光催化应用。
