Critical Review on the Mechanisms of Fe²⁺ Regeneration in the Electro-Fenton Process: Fundamentals and Boosting Strategies

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(8), P. 4635 - 4662

Published: March 14, 2023

This review presents an exhaustive overview on the mechanisms of Fe3+ cathodic reduction within context electro-Fenton (EF) process. Different strategies developed to improve rate are discussed, dividing them into two categories that regard mechanistic feature is promoted: electron transfer control and mass transport control. Boosting conversion Fe2+ via includes: (i) formation a series active sites in both carbon- metal-based materials (ii) use other emerging such as single-atom catalysis or confinement effects. Concerning enhancement regeneration by control, main routes involve application magnetic fields, pulse electrolysis, interfacial Joule heating effects, photoirradiation. Finally, challenges singled out, future prospects described. aims clarify Fe3+/Fe2+ cycling process EF process, eventually providing essential ideas for smart design highly effective systems wastewater treatment valorization at industrial scale.

Estimation methods of wetland carbon sink and factors influencing wetland carbon cycle: a review

Carbon Research, Journal Year: 2024, Volume and Issue: 3(1)

Published: May 20, 2024

Abstract In the global ecosystem, wetlands are vital carbon sinks, playing a crucial role in absorbing greenhouse gases such as dioxide and mitigating warming. Accurate estimation of wetland content is essential for research on sinks. However, cycle complex, sinking affected by climate, topography, water level conditions, vegetation types, soil other factors. This has caused significant challenges current studies, most focused impact individual factors often ignoring interaction between various factors, which further leads to uncertainty measurements. paper aims elucidate process cycle, summarize affecting explore interplay their influence aiming provide theoretical support study Additionally, this reviews advantages disadvantages measurement methods, proposes directions combining machine learning identifies existing difficulties measurement, offers suggestions serve reference future sink management.

Vertical-scale spatial influence of radial oxygen loss on rhizosphere microbial community in constructed wetland

Environment International, Journal Year: 2022, Volume and Issue: 171, P. 107690 - 107690

Published: Dec. 9, 2022

Complex interactions between plants and microorganisms form the basis of constructed wetlands (CWs) for pollutant removal. In rhizosphere, radial oxygen loss (ROL) plays a key role in activity abundance functional microorganisms. However, little has been done to explore how ROL would influence niche differentiation microbial communities at different vertical spatial scales. We demonstrate that decreases with depth, promoting an oxidation-reduction rhizosphere microecosystem CWs. The high level upper layer could support supply aerobic bacteria (Haliangium), facilitating COD (60%) NH4+-N (50%) removal, whereas enrichment denitrifiers (e.g., Hydrogenophaga Ralstonia) methanotrophs (Methanobaterium) lower stimulate denitrification. function prediction results further certified genes catalyzing nitrifying denitrification processes were significantly enhanced bottom layers, respectively, which was attributed concentration gradient rhizosphere. This study contributes unraveling effect enables improved understanding decontamination mechanisms
