MN-BASED CATALYSTS FOR SULFATE RADICAL-BASED ADVANCED OXIDATION PROCESSES: A REVIEW
Huang, J. and H. Zhang. | Environment International 133 (Part A):105141(2019)
A comprehensive review was conducted of various Mn-based materials to activate peroxymonosulfate (PMS) and peroxydisulfate (PDS) for contaminant degradation. The article covers activation mechanisms of different Mn-based catalysts; the effects of pH, inorganic ions, natural organic matter, dissolved oxygen content, temperature, and the crystallinity of the materials on the catalytic reactivity; and important instrumentations and technologies to characterize Mn-based materials and to understand the reaction mechanisms. Three common overlooks in the experimental designs for examining the PMS/PDS-MnOx systems were also discussed. Future research directions were suggested to further improve the technology and to provide guidance to develop cost-effective Mn-based materials to activate PMS/PDS.
