Presently, conventional technologies in water treatment are not efficient enough to completely mineralize refractory contaminants. In this context, the implementation of catalytic processes could be an alternative. Despite advantages provided terms kinetics transformation, selectivity, and energy saving, numerous attempts have yet led at industrial scale. This review examines investigations different scales for which controversies limitations must solved bridge gap between fundamentals practical developments. Particular attention has been paid development solar-driven some other emerging processes, such as microwave assisted catalysis, plasma-catalytic or biocatalytic remediation, taking into account their specific drawbacks. Challenges a better understanding related complexity systems coexistence various solid-liquid-gas interfaces identified.

Abstract Millions of families around the world remain vulnerable to water scarcity and have no access drinking water. Advanced oxidation processes (AOPs) are an effective way towards purification with qualified reactive oxygen species (ROSs) while impeded by high-cost tedious process in either input consumable reagent, production ROSs, pre-treatment supporting electrolyte. Herein, we couple solar light-assisted H 2 O from photo-Fenton-like reactions into a self-cyclable system using artificial leaf, achieving unassisted rate 0.77 μmol/(min·cm ) under 1 Sun AM 1.5 illumination. Furthermore, large (70 cm leaf was used for solar-driven bicarbonate-activated hydrogen peroxide (BAP) recycled catalysts real-time wastewater requirements only water, sunlight. This demonstration highlights feasibility scalability photoelectrochemical technology decentralized environmental governance applications laboratory benchtops industry.

Enhancing the peroxymonosulfate (PMS) activation efficiency to generate more radicals is vital promote Fenton-like reaction activity, however, how PMS adsorption and accelerate interfacial electron transfer boost its kinetics remains a great challenge. Herein, we prepared Cu-doped defect-rich In2 O3 (Cu-In2 /Ov ) catalysts containing asymmetric Cu-Ov -In sites for in water purification. The intrinsic catalytic activity that side-on configuration of O-O bond (Cu-O-O-In) at significantly stretches length. Meanwhile, increase density near Fermi energy level, promoting faster generating SO4 ⋅- ⋅OH. degradation rate constant tetracycline achieved by Cu-In2 31.8 times than , it shows possibility membrane reactor practical wastewater treatment.

Accelerating the rate-limiting Fe3+/Fe2+ circulation in Fenton reactions through addition of reducing agents (or co-catalysts) stands out as one most promising technologies for rapid water decontamination. However, conventional such hydroxylamine and metal sulfides are greatly restricted by three intractable challenges: (1) self-quenching effects, (2) heavy dissolution, (3) irreversible capacity decline. To this end, we, first time, introduced redox-active polymers electron shuttles to expedite cycle promote H2O2 activation. The reduction Fe3+ mainly took place at active N–H or O–H bonds a proton-coupled transfer process. As carriers, H atoms solid phase could effectively inhibit radical quenching, avoid maintain long-term via facile regeneration. Experimental density functional theory (DFT) calculation results indicated that activity different shows volcano curve trend function energy barrier, highest occupied molecular orbital–lowest unoccupied orbital (HOMO–LUMO) gap, vertical ionization potential. Thanks appropriate redox ability, polyaniline outperforms other (e.g., poypyrrole, hydroquinone resin, poly(2,6-diaminopyridine), hexaazatrinaphthalene framework) with iron up 5.5 mmol/g, which corresponds state transformation from leucoemeraldine emeraldine. Moreover, proposed system exhibited high pollutant removal efficiency flow-through reactor 8000 bed volumes without an obvious decline performance. Overall, work established green sustainable oxidation system, offers great potential practical organic wastewater remediation.

Advanced oxidation processes (AOPs) are a growing research field with large variety of different process variants and materials being tested at laboratory scale. However, despite extensive in recent years decades, many have not been transitioned to pilot- full-scale operation. One major concern the inconsistent experimental approaches applied across studies that impede identification, comparison, upscaling most promising AOPs. The aim this tutorial review is streamline future on development new solutions for advanced by providing guidance comparable scalable experiments. We discuss developments catalytic, ozone-based, radiation-driven, other AOPs, outline perspectives needs. Since standardized procedures available we propose basic rules key parameters lab-scale evaluation AOPs including selection suitable probe compounds scavengers measurement (major) reactive species. A two-phase approach assess AOP concepts proposed, consisting (i) proof-of-concept (technology readiness levels (TRL) 1-3), followed (ii) intended water matrix cost comparison an established process, applying such as UV fluence or ozone consumption (TRL 3-5). Subsequent demonstration 6-7) briefly discussed, too. Finally, highlight important tools thorough mechanistic risk assessment screening transformation products should be based chemical logic combined complementary (mass balance, calculations).
