“…Advanced oxidation processes (AOPs) are applied technologies used to efficiently treat wastewater by generating reactive oxygen species (ROS) . Depending on the production route of ROS involved in organic pollutants, AOPs are classified into ozonation, photocatalysis, , Fenton/Fenton-like catalysis, − photo-Fenton/photo-Fenton-like, − phyto-Fenton, electrochemical oxidation, sulfate radical-based AOPs, etc. As a promising AOP, the Fenton process describes a simple method for the formation of OH radicals from the decomposition of hydrogen peroxide using iron ions (Fe 2+ /Fe 3+ ) as catalysts in an acidic aqueous solution at room temperature .…”

In this work, a novel FeNi2S4/TiO2–x nanocomposite was prepared by facile hydrothermal synthesis, then comprehensively characterized by a multitechnique approach, and subsequently employed for round-the-clock (light and dark) removal of rhodamine B. Superior improvement of the morphological and thermal properties of the FeNi2S4/TiO2–x nanocomposite due to the use of sodium dodecyl sulfate was investigated. An l-ascorbic acid-assisted photo-Fenton catalyst can be employed effectively for complete rhodamine B removal at 30 min using a 10 W white-light-emitting diode (LED) source under a wide range of operating conditions compared to other reported photo-Fenton catalysts. The obtained results show a significant synergism between the nanocomposite components, which makes the total RhB removal much better than when each was used alone. This study presents a facile approach to designing a sustainable multifunctional catalyst with reusability, high catalytic activity, and environmental friendliness. Due to the photocatalytic and photo-Fenton synergism in the presence of hydrogen peroxide and ascorbic acid under visible light, there is high potential to generate more electron/hole carriers and hydroxyl radicals (•OH).

The remediation of polluted water is a major concern for public health and the environment. Catalytic removal of model organic and inorganic pollutants in water using carbon catalysts has shown promising results. In the present work, stereolithographically 3D‐printed bio‐based carbon monoliths with different textural and surface chemistry properties were used as catalysts for oxalic acid oxidation and catalyst supports for bromate reduction in continuous systems. A significant synergistic effect between ozone or dihydrogen and carbon catalyst was evidenced by mineralization of 14‐25 % of oxalic acid or reduction of 15‐45 % of bromates in the steady state, respectively. The best results were achieved with samples with the highest mesoporous surface area or, in the case of lower surface area, with samples having the strongest basic character. As materials with great potential, optimizing the textural properties of architected carbon monoliths will enable them to compete with other macro‐structured carbon catalysts.

Byproduct formation in heterogeneous catalytic ozonation processes

Abstract: Heterogeneous catalytic ozonation (HCO) is a promising advanced oxidation process (AOP) that can effectively degrade recalcitrant organic pollutants; but formation of harmful byproducts should be carefully evaluated.
