Abstract

Abstract

Low-cost, easy-to-manage, practical, and consistently compliant advanced wastewater treatment technology is the key to ensuring stable compliant discharge of coking wastewater. The heterogeneous photo-Fenton technology, characterized by low operating cost, no iron sludge burden, and low operational requirements, meets the criteria for an alternative technology. The practical application of this technology, however, hinges on the development of catalysts. In recent years, layered double hydroxides (LDHs), with large specific surface area, regular layered structure, abundant active sites, and rich hydrophilic groups, have emerged as ideal candidates for photo-Fenton catalysts. Nevertheless, the rapid recombination of photogenerated electron-hole pairs in LDHs limits their application in water treatment; while Ti₃C₂, with its excellent electrical conductivity, helps to address this drawback. In this study, the introduction of Ti₃C₂ not only increased the specific surface area of NiFeLDHs by 1.4 times but also improved the separation efficiency of photogenerated carriers. Consequently, TiC@NiFeLDH2 exhibited excellent performance in the advanced treatment of coking wastewater via photo-Fenton process, achieving a COD removal rate of 76.75% in coking wastewater within 120 min, which was 1.8 times higher than that of NiFeLDHs.
