Abstract Degradation of organic contaminants into less toxic substances is the best option to remove these compounds rather than using conventional techniques. The sulfate radical-based-advanced oxidation process an effective strategy that degrades by activating peroxymonosulfate (PMS). Such a generates singlet oxygen ( 1 O 2 ), hydroxyl $$^ \bullet \!{{{\mathrm{OH}}}}$$ ∙OH and $${{{\mathrm{SO}}}}_4^{ \bullet\! - }$$ xmlns:mml="http://www.w3.org/1998/Math/MathML">SO4∙− ) radicals. \!- distinguished its high selectivity activity toward degradation contaminates compared other Various catalysts are employed in PMS activation including layered doubled hydroxides (LDHs), which characterized their facile synthesis catalytic activity. This review article first attempt compile recent progress common pollutants aromatic compounds, pharmaceutical residues, dyes via LDH-based catalysts. pathways, reaction parameters’ influence, stability LDHs, comparisons between different investigated this work.

Persulfate (PS)-based advanced oxidation processes (AOPs) for pollutant removal have attracted extensive interest, but some controversies about the identification of reactive species were usually observed. This critical review aims to comprehensively introduce basic concepts and rectify cognitive biases appeals pay more attention experimental details in PS-AOPs, so as accurately explore reaction mechanisms. The scientifically summarizes character, generation, different species. It then highlights complexities analysis electron paramagnetic resonance, uncertainties use probes scavengers, necessities determination scavenger concentration. importance choice buffer solution, operating mode, terminator, filter membrane is also emphasized. Finally, we discuss current challenges future perspectives alleviate misinterpretations toward mechanisms PS-AOPs.

In a bid to tackle the degrading climate conditions, new age research in catalysis is predominantly focused on sustainable technologies associated with renewable energy conversion and environment purification. One of primary motivations for use low-cost, earth-abundant materials that can fulfill scale-up needs respective technologies. Cobalt (Co) based catalysts have been an indispensable part almost all areas they are often looked at as low-cost substitutes precious metal-based catalysts. context environmental applications, Co-based more commonly used reactions such hydrogen evolution reaction (HER), oxygen (OER), hydrolysis chemical hydrides, CO2 reduction (CO2RR) advanced oxidation processes (AOPs). interesting compounds Co plays diverse role facilitating different reactions. This review provides brief account significance elaborates their advancement each above-mentioned applications presents future directions An in-depth analysis gain deeper understanding systems highly desired promote breakthroughs catalysis.
