Abstract:
A MOF-derived carbon material containing CoFe alloy (Co/Fe@NPC-500) by calcining N-doped Co/Fe bimetallic MOF at a lower temperature was successfully synthesized as a cathode in electro-Fenton process for ceftazidime (CAZ) degradation. The presence of Co could accelerate the transfer of electrons from C atoms of carbon material to Fe, thus increasing the content of low-valent metals in the material, which had been demonstrated by char-acterizations and density functional theory (DFT) calculations. Thanks to the integrity of the MOF structure, the synergistic effect between Fe and Co, Co/Fe@NPC-500 cathode showed efficient removal efficiency for CAZ completely removed within 60 min and obtained a total organic carbon (TOC) removal rate of 52.1% at 90 min. Besides, based on the results of HPLC-MS and DFT calculations, the degradation pathway of CAZ was proposed. This study provides some useful information for the preparation of MOF-derived carbon materials containing low-valent metals for electro-Fenton process.
