“…The reduced degradation efficiency indicated that they competed with the target pollutants (Equations ( 5)-( 7)). However, they reacted slowly with •OH and SO 4 • − , so they had little effect on the presence of •OH and SO 4 • − in the system [41,42]. In addition to the anions mentioned above, natural organic matter (NOM) is also present in natural water.…”

The exploration of efficient, low-leaching, and recyclable transition-metal-based catalysts is of great importance for the removal of pollutants from peroxymonosulfate (PMS) in water purification processes. In this study, a bimetallic CoFe@CSC-700 composite was prepared by an alkaline gel pyrolysis reduction method using chitosan as a forming agent and applied to activate PMS to degrade levofloxacin (LEV). The leaching concentration of both cobalt and iron ions in the CoFe@CSC-700 catalyst was reduced by about 8-fold compared to the monometallic composite pellet catalyst. In addition, the removal efficiency of the CoFe@CSC-700 catalyst can still reach 90% after five cycles, showing good recyclability, recoverability and stability. Both free radical pathways (SO4·−, ·OH, and ·O2−) and non-free radical pathways (1O2) were detected in the oxidation reaction, with free radical pathways as the main contributor. The possible degradation pathways of LEV were proposed by LC-MS tests. Overall, this study provides new insights into the construction of efficient and stable PMS catalysts for wastewater treatment.

“…1f), including CO (531.4 eV), OC–O (532.5 eV) and C–O(H) (533.7 eV). 20,21 OC–O was the primary configuration, while the content of CO was relatively low. Since carboxylic groups and anhydride would decompose at high temperature, the OC–O as the dominant species for all the samples indicated that these functionalities probably regenerated through the reaction of defects with O 2 , H 2 O and CO 2 when the sample was exposed in air.…”

The synergistic effect of apoptosis and cuproptosis, along with the activation of the immune system, presents a promising approach to enhance the efficacy against triple‐negative breast cancer (TNBC). Here, two prodrugs are synthesized: a reactive oxygen species (ROS)‐responsive prodrug PEG‐TK‐DOX and a glutathione (GSH)‐responsive prodrug PEG‐DTPA‐SS‐CPT. These prodrugs are self‐assembled and chelated Cu2+ to prepare nanoparticle PCD@Cu that simultaneously loaded doxorubicin (DOX), camptothecin (CPT), and Cu2+. The elevated levels of ROS and GSH in TNBC cells disrupted the PCD@Cu structure, leading to the release of Cu+, DOX, and CPT and the depletion of GSH. DOX and CPT triggered apoptosis with immunogenic cell death (ICD) in TNBC cells. Simultaneously, PCD@Cu downregulated the expression of copper transporting ATPase 2 (ATP7B), causing a significant accumulation of copper ions in TNBC cells. This further induced the aggregation of lipoylated dihydrolipoamide S‐acetyltransferase (DLAT) and downregulation of iron‐sulfur (Fe‐S) cluster proteins, ultimately leading to cuproptosis and ICD in TNBC. In vitro and in vivo experiments confirmed that PCD@Cu induced apoptosis and cuproptosis in TNBC and activated the immune system, demonstrating strong anti‐tumor capabilities. Moreover, PCD@Cu exhibited an excellent biosafety profile. Overall, this study provides a promising strategy for effective TNBC therapy.
