<p>Anthropogenic climate and environmental changes increasingly threaten the sustainability of life on Earth, hindering sustainable development human societies. These detrimental ecological are driven by activities that have elevated atmospheric levels greenhouse gases toxic substances, increased inorganic organic pollutants in water bodies, led to accumulation solid waste soils. Over next two three decades, impacts change, pollution, soil contamination expected intensify, posing increasing risks health global stability. Considering these trends, it is essential implement robust mitigation adaptation strategies. This paper analyzes pollution problems from perspectives atmospheric, water, contamination. It summarizes current research heterogeneous catalysis for treating gaseous, liquid, phases, with an emphasis key challenges applying catalytic conversion technologies cost-effective industrial settings. Finally, strategies mitigating via discussed material flow, energy data flow. aims offer scientific insights enhance future practice remediation.</p>

N‐, S‐Codoped Porous Carbon With Trace Single‐Atom Fe for Enhanced Oxygen Reduction With Robust Poison Resistance and Efficient Rechargeable Zinc–Air Battery

Carbon Neutralization, Год журнала: 2025, Номер 4(2)

Опубликована: Фев. 11, 2025

ABSTRACT Pt‐based electrocatalysts in oxygen reduction reaction (ORR) have severely hindered large‐scale application of relevant energy technologies. Carbon composites codoped with heteroatoms and transition metals are considered the most likely alternatives to Pt, but they still limitation poor tolerance poisons. Thus, exploration advanced superior activity high poison resistance is great significance practical applications. Herein, a low‐cost lysozyme was first directly used fabricate single‐atomic Fe anchored on porous N‐, S‐codoped carbon (Fe‐PNSC) using simple “mix‐and‐pyrolyze” method, which has honeycomb‐like structure large surface area 957.69 m²/g, adequate pores 0.71 cm³/g, rich heteroatom doping 4.66 at.% N, 1.9 S, 0.18 wt.% Fe. Accordingly, Fe‐PNSC displays an onset potential 1.08 V half‐wave 0.86 for ORR, strong stability 96.87% current retention, robust methanol various poisons, all outperforming Pt/C. Additionally, Fe‐PNSC–based zinc–air battery shows peak power density 122.2 mW cm −2 , good specific capacity 787 mAh g Zn −1 975.9 Wh kg respectively, remarkable rechargeable 300 h, Pt/C‐based ones.

Antiviral drugs, in particular those used to treat COVID-19, have been categorized as emerging pollutants recent years due their persistent presence water/wastewater. They identified environmental matrices all over the world, proving that current treatment methods cannot eliminate them from In this study, degradation of favipiravir (FAV) and ecotoxicity changes different water were investigated using UV, UV/H2O2, UV/Co-doped ZnS quantum dots (QDs) photocatalytic processes. The effects initial FAV concentration, matrices, pH, H2O2 catalyst amount on rate evaluated. Initial concentrations (50, 100, 150 μg/L) a slight effect rate. matrix composition significantly reduced rates efficiencies for QDs processes following order: wastewater plant (WWTP) effluent > tap (TW) distilled (DW). pH (4.0, 5.0, 7.0, 9.0) had remarkable enhanced 86.3 98.1% with increasing 4.0 9.0 ionization degree UV process. maximum was obtained at 7.0 removal 93.9 100% UV/H2O2 processes, respectively. Transformation products determined toxicity algae increased 50 μg/L water. Growth inhibition 50, 15.1, 33.3, 36.3% 96 h, respectively, without any treatment. After 60 min process, growth decreased below 0.5% regardless concentration. Overall, process is effective degrading aqueous matrices; however, an step required remove natural organic matter actual matrices.

Electrocatalytic Oxygen Self-Sufficiency System Enables Singlet Oxygen Production for Water Decontamination

ACS ES&T Water, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 19, 2024

Electrochemical advanced oxidation process represents a promising strategy for water decontamination, but the parasitic anodic side oxygen evolution reaction always causes low energy utilization efficiency. In this study, we address limitation of developing an electrocatalytic self-sufficiency system. This system established integrated that ran solely on O2 produced by evolution, followed transformation into H2O2 at nanoconfined Fe2O3 cathode, which then led to generation 1O2. The performance decontamination was evaluated using tetracycline (TC), bisphenol A (BPA), and perfluorooctanoic acid (PFOA) as model emerging contaminants. When polarization applied 2.0 V vs standard hydrogen electrode, removal TC, BPA, PFOA with flow rate 10 mL min–1 could reach 90.1%, 92.1%, 62.2%, respectively. Electron spin resonance radical quenching results indicated 1O2 main reactive species TC BPA decomposition, whereas decomposition contributed direct electron transfer. intermediate toxicity predicted be reduced, excellent anti-interference ability proved in actual water. These findings suggest reagent-free oxygen-dependent sustainable decontamination.
