Summary: In this study, a modular design protocol was developed to synthesize a family of ultrafine alloy nanoclusters embedded in a nitrogen-enriched carbon framework for the treatment of pharmaceutical contamination issues. By engineering the fine structure of nitrogen-enriched carbon and the interfacial interaction with bimetallic nanoclusters, the overgrowth of nanoclusters was largely suppressed, resulting in highly dispersed, well-alloyed nanoclusters. The alloying of Fe-0 with other metals optimized the electron flow, chemical stability, and catalytic property, leading to excellent degradation performance for doxorubicin. The outstanding degradation ability of the nanoclusters was attributed to the enhanced affinity and efficient electron transfer.

Summary: The low-cost preparation of iron phosphide from pickling waste liquor was achieved through a two-step reaction. The iron phosphide coupled with peroxymonosulfate exhibited efficient degradation of Orange G, with the main role played by sulfate radicals. The catalyst showed excellent recycling stability with a catalytic efficiency of 95% after five cycles.

Summary: A novel material of self-shaped ZnO-embedded biomass carbon foam pellets (ZnO@BCFPs) was synthesized and used in a three-dimensional electro-peroxone system for metronidazole degradation. The addition of ZnO@BCFPs particle electrodes improved the removal efficiency of metronidazole and reduced energy consumption, forming numerous tiny electrolytic cells.

Summary: In this study, pure zero-valent iron (ZVI) supported on silica and starch was used to enhance the activation of persulfate (PS) for tetracycline degradation. The synthesized catalysts were characterized and their physical and chemical properties were evaluated. The addition of light and the modified ZVI-Si/PS system improved the degradation performance of tetracycline. The optimal operating parameters were determined by response surface methodology, and the degradation pathway and mechanism were explained. Tetracycline degradation was influenced by the presence of inorganic ions and dissolved organic matter in different matrices.

Summary: This paper discusses the efficiency and mechanism of using nitrilotriacetic acid (NTA) as a complexing agent to enhance the zero-valent iron (Fe0)/peroxymonosulfate (PMS) system for the removal of sulfamethazine (SMZ) from water. The research results show that the addition of NTA increases the soluble iron content and the decomposition rate of PMS. Additionally, different inorganic ions, such as Cl-, have been found to affect the degradation of SMZ. In actual water bodies, the PMS/Fe0/NTA system can degrade SMZ up to 79.36%. Toxicity tests demonstrate a decrease in the inhibition rate of luminescent bacteria after degradation.

Summary: This study highlights the significance of structure regulation in the O-O bond formation process in binuclear iron catalysts. While some catalysts proceed via oxo-oxo coupling, others with rigid ligands show negligible catalytic activity due to limited isomerization and rotation of Fe=O moieties.

Summary: In this work, three stable titanium-oxo clusters modified with different ligands were constructed. These clusters demonstrated tunable light-harvesting and charge transfer capacities, enabling efficient photoelectrocatalytic reactions. The cluster Ti12Fc2Ac4, modified with bifunctionalized ligands, showed better performance in the degradation of 4-chlorophenol (4-CP) and hydrogen generation compared to the other two clusters. This study not only presents an effective combination of organic pollutant degradation and hydrogen evolution reaction using crystalline coordination clusters but also introduces a new photoelectrocatalytic application for these compounds.
