TL;DR: In this paper, the authors reported that magnesium oxides (MgO) in CuOMgO/Fe3O4 not only enhanced the catalytic properties but also switched the free radical peroxymonosulfate (PMS)-activated process into the 1O2 based nonradical process.

TL;DR: In this paper, the authors found the incorporation of Cu demonstrated the most remarkable promotional effect to Co oxides comparing with Fe and Mn in PMS activation, and no spinel structure of mixed metals was found, while the synergism between oxides of Cu and Co was observed on various supports including MgAl layered double hydroxides, mesoporous MnO2 and ZnO.

TL;DR: In this article, a series of Co9S8 nanorods catalysts from Co3O4 precursor with different S doping ratios were reported, and the catalytic process gradually switched from non-radical (1O2) into radical (SO4 −) with the increase of S doping ratio.

TL;DR: Recently, various non-radical oxidation mechanisms different from traditional free radicals have been discovered in peroxymonosulfate (PMS)-based heterogeneous catalytic system as discussed by the authors, and the challenges and strategies for the further development of these oxidation mechanisms, as well as the research and application prospects are proposed.

TL;DR: Red mud-sewage sludge derived biochar was synthesized and employed as the heterogenous activator of peroxymonosulfate (PMS) for SMX degradation, suggesting its potential full-scale application of environmental remediation.
