[2][3][4] It has been reported that PMS is more easily activated than persulfate on account of its asymmetric molecular structure and shorter O-O bond length. 5,6 Heat, ultraviolet (UV), ultrasound (US), electrochemical oxidation, alkali, photogenerated electrons, radiation, carbon-based materials, and transition metals, have all been developed as PMS activation strategies thus far.…”

“…This view is strongly supported by the recent literature reports. 3,18 Ma et al have loaded MgFe-LDH on biochar derived from sludge by the hydrothermal method to activate PMS toward doxycycline (DOX) degradation, and the degradation rate reaches 88.76% within 120 min, higher than that of MgFe-LDH alone. 3 Ye et al have developed a BC/CoFe-LDH/PMS system with a 38% improvement in dimethyl phthalate (DMP) degradation efficiency compared to the LDH/PMS system alone.…”

Antibiotic contamination in water bodies poses ecological risks to aquatic organisms and humans and is a global environmental issue. Persulfate-based advanced oxidation processes (PS-AOPs) are efficient for the removal of antibiotics. Sustainable biochar materials have emerged as potential candidates as persulfates (Peroxymonosulfate (PMS) and Peroxydisulfate (PDS)) activation catalysts to degrade antibiotics. In this review, the feasibility of pristine biochar and modified biochar (non-metal heteroatom-doped biochar and metal-loaded biochar) for the removal of antibiotics in PS-AOPs is evaluated through a critical analysis of recent research. The removal performances of biochar materials, the underlying mechanisms, and active sites involved in the reactions are studied. Lastly, sustainability considerations for future biochar research, including Sustainable Development Goals, technical feasibility, toxicity assessment, economic and life cycle assessment, are discussed to promote the large-scale application of biochar/PS technology. This is in line with the global trends in ensuring sustainable production.

Peroxymonosulfate (PMS) based advanced oxidation processes (AOPs) are effective in degrading refractory organic pollutants in water. The unique internal chemical tunability of Prussian blue analogues (PBAs), a type of metal‐organic framework materials (MOFs), makes them promising catalysts for PMS‐AOPs. However, the pristine PBA is limited in practical application due to its structural instability and easy leaching of metal ions. To this end, various methods have been developed to enhance the catalytic performance of PBAs. In this paper, the recent advances in the modification and composite strategies of PBA catalysts are systematically reviewed. PBA modification by the regulation of synthesis conditions and post‐synthesis treatment, along with composite strategies involving metal and non‐metal based materials are introduced. The structural morphology improvement, physical and chemical property adjustment, vacancy design and crystal surface modulation of PBAs induced by these modification and composite strategies are discussed in depth. In addition, the performance of the modified and composite catalysts to activate PMS for organic pollutant degradation is demonstrated. The radical pathway via SO4•‐, •OH and O2•‐, non‐radical pathway through 1O2, electron transfer process and high‐valence metal‐oxygen species, or a combination of radical and non‐radical pathways are revealed in PMS‐AOPs with PBAs and their derivatives as catalysts.
