In this study, rare-earth orthoferrites LnFeO<sub>3</sub> were synthesized using a facile hydrothermal reaction and their visible-light-induced photo-Fenton degradation of organics was optimized through Ln variation (Ln = La, Pr, or Gd). The morphological, structural, and chemical characteristics of as-prepared samples were examined in detail by using different methods, including XRD, SEM, TEM, XPS, etc. On the other side, under visible light illumination, the photo-Fenton-like catalytic activities of LnFeO<sub>3</sub> were assessed in terms of the removal of selected organic models, i.e., pharmaceuticals (ketoprofen and tetracycline) and dyes (rhodamine B and methyl orange). As compared with PrFeO<sub>3</sub> or GdFeO<sub>3</sub>, the sample of LaFeO<sub>3</sub> displayed more structural distortion, larger specific surface area, and narrower band gap, resulting in its higher photo-Fenton-like catalytic activity toward the degradation of organics. In organic-containing solution, in which the initial solution pH = 5, catalyst dosage = 1 g/L and H<sub>2</sub>O<sub>2</sub> concentration = 10 mM, 98.2% of rhodamine B, 31.1% of methyl orange, 67.7% of ketoprofen, or 96.4% of tetracycline was removed after 90-min exposure to simulated visible light. Our findings revealed that variation of Ln site on rare-earth orthoferrites was an effective strategy for optimizing their organic removal via visible-light-induced photo-Fenton reaction.

Cu-doped LaFeO3 was prepared by a facile hydrothermal reaction and evaluated as highly efficient photo-Fenton-like catalyst under visible light for organic degradation. The use of LFO-15Cu (LaFe0.85Cu0.15O3), which possessed favourable physicochemical characteristics, could achieve almost complete decolourisation of cation and anion dyes within 60 min visible light irradiation. The mechanism study by ESR spectroscopy confirmed LFO-15Cu could activate H2O2 under visible light to generate many more hydroxyl radicals than LFO (LaFeO3). LFO-15Cu was proven with excellent stability and reusability; and in turn showed great potential for use in continuous photo-Fenton-like degradation of organic in water under visible light.

The rapidly rising demand for lithium has made the recycling of spent lithium-ion battery highly attractive. However, the conventional process has faced environmental problems due to gas and wastewater generation, high-energy consumption, and the use of strong acids/alkalis for an extended period of time. An innovative recycling technology exploiting the mechanochemical process is proposed to overcome the drawbacks of the conventional process and improve the metal recovery from spent batteries. In general, the unique mechanism by mechanochemical reaction enables metal extraction with non-hazardous materials and minimal use of solvents at ambient temperature. This emerging technique can be combined with hydrometallurgical processes and offers potential for reagent regeneration. This article reviews different recycling technologies for spent lithium-ion battery cathode materials, particularly the mechanochemical process, to achieve circular economy in spent battery recycling and enhance lithium recovery.
