A facile and efficient strategy was introduced to prepare p-tolylsulfonyl-b-cyclodextrin (TsO-b-CD). Subsequently, the smart and recyclable Fe3O4@APTES-b-CD nanoparticles were prepared via betweenFe3O4@APTES and TsO-b-CD. And then, the structures of TsO-b-CD and Fe3O4@APTES-b-CD were characterizedand analyzed. Finally, the Fe3O4@APTES-b-CD nanoparticles was utilized as a heterogeneousFenton-like catalyst. The catalytic performance of Fe3O4@APTES-b-CD for 2-chloro-4-nitrophenol (4-C-2-NP) were assessed and studied. Accordingly, the degradation process of 4-C-2-NP fitted the pseudofirst-order kinetics model. In the meantime, the catalytic activity of Fe3O4@APTES-b-CD was higher thanthat of Fe3O4@APTES-a-CD or Fe3O4@APTES-c-CD. More importantly, the Fe3O4@APTES-b-CD possessedgood regeneration and reuse ability. In addition, the possible reaction route and degradation mechanismwere proposed with synergistic effects. Consequently, the Fe3O4@APTES-b-CD can potentially serve as asmart and recyclable heterogeneous Fenton-like catalyst.
