description | Peroxymonosulfate (PMS) activation has gained increasing attention for its water remediation. In this work, carbon nanotube-supported FeCo<sub>2</sub>O<sub>4</sub> nanoparticles (FeCo<sub>2</sub>O<sub>4</sub>/CNT) were prepared and showed tremendous potential as a catalyst for PMS activation. The synergistic effect between FeCo<sub>2</sub>O<sub>4</sub> and CNT in FeCo<sub>2</sub>O<sub>4</sub>/CNT promotes its better catalytic performance than individual CNT or FeCo<sub>2</sub>O<sub>4</sub>. The synthesized FeCo<sub>2</sub>O<sub>4</sub>/CNT could reach 100% phenol removal with a <i>k</i> value of 0.30 min<sup>−1</sup> within 15 min ([PMS] = 0.3 g L<sup>−1</sup>, [FeCo<sub>2</sub>O<sub>4</sub>/CNT] = 0.3 g L<sup>−1</sup>). FeCo<sub>2</sub>O<sub>4</sub>/CNT can adapt well to a wide pH range (4–9) and a complex water component (with inorganic ions or organic matter). Moreover, the catalytic mechanism investigation suggested that both radical and non-radical pathways are accountable for the efficient removal of phenol. |
