Catalysts, Год журнала: 2024, Номер 14(4), С. 267 - 267

Опубликована: Апрель 17, 2024

The use of hydrogen peroxide (produced in situ or ex situ) as the main agent oxidative processes environmental pollutant removal is widely studied. degradation water pollutants, such dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview more recent methods developed to apply mediated H2O2 other reactive oxygen species (ROS) catalysis, with particular attention strategies (Fenton-like Bio-Fenton, photo- electro-catalysis) materials employed. A wide discussion about characteristics specifically studied for activation, well their chemical composition morphology, was carried out. Moreover, interesting generation enzymes were also presented efficiency applicability compared Fenton electro-Fenton discussed above. Bio-Fenton bi-enzymatic ROS seems be attractive scalable, although not yet applied full-scale plants. critical feasibility, criticalities, perspectives all considered completes this review.

Textile Wastewater Coupled Treatment Implementing Enhanced Ozonation with Fenton-like Processes and Phytoremediation

Catalysts, Год журнала: 2025, Номер 15(1), С. 43 - 43

Опубликована: Янв. 6, 2025

In this contribution, we described how phytoremediation using M. aquaticum is feasible with coupled ozonation/Fenton-like processes in real wastewater from the denim textile industry, purpose of removing color and, therefore, highly polluting particles. For process, pHs 3 and 9 were evaluated a copper-enriched pumice to activate catalytic carried out Fenton-like reactions. Subsequently, was completely degrade by-products generated ozone/Fenton-like process. Plant health controlled through determination chlorophylls carotenes. All analyses monitored by COD, UV–Vis spectrophotometry for determinations quantification oxidizable organic matter, SEM/EDS characterization material XPS corroborate oxidation state copper that gives rise radical species. The results indicate that, at pH 3.0, ozonation process PMPCu catalyst 1 g/L most efficient, achieving percentage removal 86.79 ± 1.3% COD 76.19%, which consistent optimization analysis experimental design. residual its degradation eliminated phytoremediation.

Ultrasonic Activation of Au Nanoclusters/TiO2: Tuning Hydroxyl Radical Production Through Frequency and Nanocluster Size

Molecules, Год журнала: 2025, Номер 30(3), С. 541 - 541

Опубликована: Янв. 24, 2025

This study explores the sonocatalytic activity of gold nanoclusters (Au NCs) combined with titanium dioxide (TiO2) nanoparticles, forming Au NCs/TiO2 composites. The hybrid material significantly enhances hydroxyl radical (•OH) generation under ultrasonic conditions, attributed to high-energy cavitation bubbles formed during ultrasonication. effects frequency (200, 430, and 950 kHz) power were systematically evaluated on Au144/TiO2 composites, identifying 430 kHz as optimal for •OH production due its efficient energy. Au144 NCs function electron traps, reducing electron–hole recombination in ultrasonically activated TiO2, thereby improving charge separation enhancing generation. Size-dependent also studied, showing an efficiency trend > Au25 plasmonic nanoparticles bare TiO2. These findings highlight importance ultrasonication NC size optimizing performance providing valuable insights designing advanced sonocatalysts applications chemical synthesis, environmental remediation, biomedical fields.
