Summary: This study investigates the improved catalytic activity of Fe3O4-decorated glassy zero-valent iron (GZVI) through a low-cost ball milling technique. The addition of 10% Fe3O4 to GZVI resulted in the best surface morphology and highest catalytic efficiency. The Fe3O4/GZVI catalyst exhibited excellent stability and reusability, achieving a 97.37% degradation of p-nitrophenol within 15 minutes. The formation of a galvanic cell between Fe3O4 and GZVI played a crucial role in promoting electron transfer and hydroxyl radical generation, thereby enhancing the pollutant degradation process.

Summary: Introducing crystal defects into iron-based metal-organic frameworks (Fe-MOFs) is a promising strategy to enhance Fenton-like performance. However, developing a facile and effective strategy to construct defective Fe-MOFs as highly efficient Fenton-like catalysts is still challenging. In this study, MIL-100(Fe) (Def-MIL-100 (Fe)) with missing ligand defects was synthesized by a simple heterogeneous reaction, and it exhibited significantly higher Fenton-like activity compared to the perfect MIL-100(Fe). The missing ligand defects played a key role in promoting fast H2O2 adsorption, accelerating electron transfer, and improving OH generation and utilization efficiency.

Summary: In this study, molybdenum sulfide (MoS2) was used as a co-catalyst to enhance the performance of the nanoscale zero-valent iron (nZVI) based Fenton-like process for Rhodamine B (RhB) degradation. The addition of MoS2 significantly accelerated H2O2 decomposition and increased the RhB degradation rate constant compared to the conventional Fenton process. Furthermore, the effective pH range was expanded to 9.0 with a high removal rate of RhB. The MoS2/nZVI system exhibited stability and reusability. The involvement of various reactive species, such as hydroxyl radicals, superoxide anions, and singlet oxygen, was confirmed through quenching tests and electron paramagnetic resonance. The toxicity of degradation products decreased after treatment, indicating the potential of this MoS2 co-catalytic nZVI-based Fenton-like process for organic wastewater treatment.

Summary: In this study, the performance and mechanism of the S-nZVI/Fe2+ system for oxygen activation to remove emerging contaminants (ECs) were comprehensively explored. The S-nZVI/Fe2+ system showed significantly higher kinetic rate constant for the oxidative degradation of ECs compared to other systems, and demonstrated high efficiency in EC mineralization and detoxification. The addition of Fe2+ promoted the corrosion of S-nZVI, leading to improved O2 activation and consecutive single-electron O2 activation for & BULL;OH production. The pH-insensitive Fenton-like degradation process by S-nZVI/Fe2+ indicated its robust performance over a wide pH range. This study provides valuable insights for the practical implementation of nZVI-based technology in achieving high-efficiency removal of ECs from water.

Summary: In this study, a comparison of different iron minerals and zero-valent metals as catalysts for the Fenton-like process for the removal of imidacloprid was conducted. Zero-valent iron (ZVI) showed the highest activity among the recyclable solid catalysts, while pyrite exhibited stability and sustainable ability, making it a promising catalyst for Fenton-like reactions. The system predominantly proceeded through a homogeneous route via dissolved Fe or Cu ions, with low possibility of causing secondary pollution of toxic metals for most tested catalysts.

Summary: This study investigates the effect of zero-valent iron nanoparticles (nZVI) on different bacteriophages and suggests that nZVI can be an environmentally friendly, inexpensive, and efficient method of phage inactivation. The reduction of plaque-forming units varied depending on the bacteriophages, and the importance of oxidation of nZVI versus the release of Fe2+/Fe3+ ions is discussed. The proposed mechanism of action involves redox reactions, virion adsorption, and the impact of released iron ions.
