“…Fe 3 O 4 is especially attractive for this process as the octahedral sites can, as previously stated, hold both Fe 2+ and Fe 3+ and thus can undergo a photo‐Fenton process while remaining in the heterogenous state. A typical Fenton process follows equations 1–9 [29] . The rate of (1) is several orders of magnitude larger than that of (3), which is the rate determining step.…”

Sulfurized Steel Nanoparticles: A Degradative Byproduct of ZrS₂CVD with Promising Fenton‐Type Catalytic Activity

Chemical vapor deposition (CVD), is an attractive method for the growth of two-dimensional (2D) materials such as transition metal dichalcogenides (TMDCs). However, it is an inherently wasteful process; the majority of chemical precursors end up in the waste stream and their corrosive nature deteriorates reactor components. While exploring the thermal CVD growth of ZrS 2 , the resulting corrosion build up on the downstream stainless-steel (SS) reactor components was collected and studied. Characterization of this material confirmed the presence of nanoplates composed of evenly distributed elements that constitute SS along with Cl, S, and trace Zr from the precursors. The material proved remarkably active as a photo-Fenton type catalyst for the aqueous degradation of methylene blue. Harvesting and upcycling this overlooked nanomaterial will reduce waste and concomitantly add value and enhance the sustainability of the overall TMDC fabrication process.

“…An important reason for the requirement of a large amount of Fe(II) in the FP is due to the slow kinetic from Fe(III) to Fe(II). , The promotion of Fe(III) to Fe(II) could reduce the usage amount of Fe(II). During the process of EB radiation, reductive species such as hydrated electron and oxidative species such as hydroxyl radicals can be generated simultaneously with almost equal yields .…”

This study developed a novel electron beam (EB) and Fenton process (FP) for the advanced treatment of dyeing wastewater by combining EB radiation with the FP. In the presence of 0.1 mM Fe(II) and 0.1 mM H2O2, the mineralization efficiency of Rhodamine B was 59.21% at a dose of 2 kGy, which is higher than single EB radiation and the FP, due to the interaction of hydrated electron with Fe(II) and H2O2, hydrated electron enhanced the activation of H2O2 and the conversion from Fe(III) to Fe(II) in the EB radiation process. For the actual dyeing wastewater with 255 mg/L COD and 150 times color, the COD decreased to 52 mg/L, and the color decreased to 10 times after EB & FP treatment. In addition, EB & FP was used as an advanced treatment process in practical application to treat the dyeing wastewater from a knitting factory and showed satisfactory performance. The treatment cost of EB & FP was estimated to be 1.5 ¥ per ton wastewater. In summary, EB & FP possesses strong oxidation capacity and low operational cost with the maximum treatment capacity of 5000 m3 per day per electron accelerator, which could provide a solution for the treatment of recalcitrant dyeing wastewater.

Defects on CoS_2−x: Tuning Redox Reactions for Sustainable Degradation of Organic Pollutants

It is important to develop self‐producing reactive oxygen species (ROSs) systems and maintain the continuous and effective degradation of organic pollutants. Herein, for the first time, a system of ultrasound‐treated CoS2−x mixed with Fe2+ is constructed to sustainably release singlet oxygen (1O2) for the effective degradation of various organic pollutants, including dyes, phenols, and antibiotics. Ultrasonic treatment produces defects on the surface of CoS2 which promote the production of ROSs and the circulation of Fe3+/Fe2+. With the help of Co4+/Co3+ exposed on the surface of CoS2−x, the directional conversion of superoxide radical (.O2−) to 1O2 is realized. The CoS2−x/Fe2+ system can degrade organic pollutants efficiently for up to 30 days, which is significantly better than the currently recognized CuPx system (<3 days). Therefore, CoS2−x provides a new choice for the long‐term remediation of organic pollutants in controlling large area river pollution.
