摘要：We demonstrate a highly efficient Fe/N/C electrocatalyst for oxygen reduction reaction (ORR) which was prepared through MgO template directed approach followed by pyrolysis of iron salt and nitrogen-rich carbon precursors. The Fe/N/C electrocatalyst displays a porous carbon structure with iron atoms, Fe3C nanoparticles and Fe-Nx as active sites which endow the electrocatalyst with plenty of accessible and active sites that are favorable for the enhanced electrocatalytic activity towards ORR. The as-obtained Fe/N/C electrocatalyst exhibits excellent electrocatalytic performance. A process integration of catalysis and oxidation is proposed to achieve the removal of TOC from high strength phenolic wastewater, which original TOC is 7600 mg/1. In this study, the influence of alkali precipitation on oxidation of strength phenolic wastewater with Fe/N/C as catalyst was investigated. Adding the Fe/N/C electrocatalyst increased TOC removal. TOC removal was 98.3% in the catalytic supercritical water oxidation (CSCWO) over Fe/N/C electrocatalyst.
