摘要
The heterogeneous, sulfate radical-based AOPs (SR-AOPs) have emerged over the last decade as a highly potent technology for the removal of various organic contaminants from water. This review aims to summarize the rapid development of the various heterogeneous catalysts developed for peroxymonosulfate (PMS) activation, destined for the degradation of organic contaminants. We cover catalysts such as metal and bi-metallic oxides, supported noble/non-noble metal catalysts, carbonaceous-based materials, layered double hydroxides, metal organic frameworks, zeolite and perovskite-based catalysts, used as effective activators for the activation of PMS. The radical and non-radical pathways, as well as the role of each radical in the reaction mechanism were discussed in detail. In addition, the physicochemical properties of the catalyst influencing the PMS activation mechanisms were summarized. Finally, a critical comparison of the main categories of heterogeneous catalysts is presented, while the opportunities and shortcomings of their conception and application are also discussed.
