Metal–organic frameworks (MOFs) as selectivity regulators for catalytic reactions have attracted much attention, especially MOFs and metal nanoparticle (NP) shelled structures, e.g., MOFs@NPs@MOFs. Nevertheless, making hydrophilic MOF shells for gathering hydrophobic reactants is challenging. Described here is a new and viable approach employing conjugated micro‐ and mesoporous polymers with iron(III)
金属有机骨架(MOF)作为催化反应的选择性调节剂已经引起了广泛的关注,特别是MOF和金属纳米颗粒(NP)带壳结构,例如MOFs @ NPs @ MOFs。然而,制造用于收集疏水性反应物的亲水性MOF壳具有挑战性。本文介绍了一种新的可行方法,该方法将共轭微孔和中孔聚合物与卟啉铁(III)(FeP-CMP)用作制造MIL-101 @ Pt @ FeP-CMP的新壳体。它不仅是疏水的和多孔的,用于富集反应物,而且还具有激活C = O键的铁位,从而调节肉桂醛加氢中肉桂醇的选择性。有趣的是,MIL-101 @ Pt @ FeP-CMP海绵可以实现较高的周转频率(1516.1 h -1),对肉桂醇的选择性为97.3%,转化率为97.6%。
