- Abstract
Sodium percarbonate (SPC) is recently developed as the most promising alternative for liquid H2O2 on the sewage treatment, because of its excellent explosion-resistance, high stability and safety. Herein, we first designed and synthesized a series of Mo-based/carbon nanocomposites (MoCNs) with core–shell and nanorod structures, derived from metal organic frameworks, for activating percarbonate in the efficient removal of tetracycline. The detailed characterizations confirmed MoCN-600 (a mixture of MoO3, MoC and MoO2) exhibited a nanorod structure with outer Zn and Co co-doped carbon layer. MoCN-600/SPC system exhibited a strong anti-interference ability for common anions and organic matter in TC degradation. Quenching tests and EPR results demonstrated that ·CO3− was the dominating reactive oxygen species in MoCN-600/SPC system. Compared with H2O2, MoCN-600/SPC system presented the excellent catalytic performance in TC degradation at a wider pH range. This work not only provides an efficient method for the synthesis of Mo-based heterogeneous catalysts, but also offers an excellent catalytic system for antibiotics removal.
