Summary: Sulfur-functionalized CoMn2O4 (S-CoMn2O4) was prepared and found to have significantly improved catalytic activity compared to CoMn2O4. The best catalytic performance was achieved with S-CoMn2O4(5.00%) catalyst modified with 5.00% sulfur. This catalyst removed 30 mg/L rhodamine B in 18 minutes. Singlet oxygen and sulfate radicals were identified as the primary active species. The incorporation of sulfur led to the formation of oxygen vacancies and sulfate groups on the surface of CoMn2O4, promoting the generation of more active species. The synergy between Co and Mn ions and high electron transfer mobility were also responsible for the enhanced degradation performance of S-CoMn2O4(5.00%).

Summary: The heterogeneous photo-Fenton-like process is becoming a promising method for treating antibiotics-containing wastewater. A composite catalyst, PB modified CeO2, was prepared and showed improved catalytic degradation ability for norfloxacin oxidation. The doping of PB led to increased oxygen vacancies and surface area of CeO2, facilitating electron transfer and improving the separation rate of electron-hole pairs. The PB/CeO2 composite exhibited good reactivity over a wide pH range and could be used as an efficient catalyst for organic contaminants degradation.

Summary: Urea oxidation reaction (UOR) has the potential to replace oxygen evolution reaction (OER) in water splitting technology due to its lower theoretical potential, resulting in simultaneous hydrogen generation and water purification. In this study, we synthesized aNi(OH)2 porous nanoflowers (a-Ni(OH)2-PNF) using ZIF-67 as a template. The presence of nanopores on a-Ni(OH)2 nanosheets, attributed to the Kirkendall effect, facilitates the formation of oxygen vacancies and reduces mass transfer resistance during UOR catalysis. Additionally, a-Ni(OH)2-PNF exhibits a lower voltage requirement for catalyzing UOR and exceptional stability during 20 hours of catalysis.

Summary: A novel heterogeneous Fenton-like catalyst, HS-CuFe2O4-sigma, was designed in this study to efficiently remove the pollutant ciprofloxacin. The efficient catalytic performance of HS-CuFe2O4-sigma is attributed to the synergistic effect of oxygen vacancies and the nanoconfinement of the catalyst's special hollow structure.

Summary: The oxidation rates and adsorption capacity of antimonite (Sb (III)) on six different structures of manganese oxides (MnxOy) were investigated. Higher reduction potential and specific surface area favored faster Sb(III) oxidation, while Mn(III) and oxygen vacancies exhibited a synergistic effect on Sb(III) oxidation. The results provide mechanistic insight into the fate of Sb(III) in Mn-rich environments.

Summary: This study successfully utilized one-step biosynthesized iron nanoparticles/reduced graphene oxide (FeNPs/rGO) by tea extract to enhance the removal of 17 alpha-estradiol (alpha E-2). The results showed that FeNPs/rGO achieved a removal rate of 56.1% for alpha E-2, while the removal rates for rGO and FeNPs alone were only 25.4% and 45.4% respectively. The combination of adsorption and Fenton-like oxidation effectively enhanced the removal of alpha E-2.

Summary: In this study, the degradation and mineralization of the drug norfloxacin (NFX) were investigated in a model solution under acidic conditions using an electrochemical process. The results showed that anodic oxidation with active chlorine (AO-HClO) outperformed other treatment methods due to the formation of refractory complexes and the conversion of HClO. Solar photoelectro-Fenton (SPEF-HClO) was the most effective method among Fenton-based treatments. The degradation sequence of NFX was proposed and several primary and stable by-products were identified.

Summary: The efficient mineralization of toxic sulfanilamide was achieved by using NiFe-layered double hydroxide (NiFe-LDH) nanosheets array with abundant oxygen vacancies grown on exfoliated graphene. Through electro-Fenton process, the abundant oxygen vacancies in NiFe-LDH/EG-OVr rapidly generated hydrogen peroxide (H2O2) and hydroxyl radical (center dot OH), leading to 98% mineralization of sulfanilamide within 80 minutes. The main active oxidation species in the efficient mineralization of sulfanilamide was identified as hydroxyl radicals.

Summary: A novel process combining gallic acid (GA) and mixed culture bioleaching (MCB) was designed to enhance the removal of metals from spent lithium-ion batteries (LIBs). The process achieved 98.03% Co and 98.02% Li leaching from spent LIBs, reducing the biotoxicity, phytotoxicity, and leaching toxicity of the batteries. Mechanism analysis showed that functional microorganisms adapted to the leaching system through various strategies, aiding in the release of Co and Li. This study provides valuable insight into simultaneously enhancing metal extraction and reducing environmental pollution from spent LIBs.
