Abstract The electro‐Fenton (EF) process is an advanced oxidation technology with significant potential; however, it limited by two steps: generation and activation of H 2 O . In contrast to the production via electrochemical two‐electron oxygen reduction reaction (ORR), three‐electron (3e − ) ORR can directly activate molecular yield hydroxyl radical (⋅OH), thus breaking through conceptual operational limitations traditional EF reaction. Therefore, 3e a vital for efficiently producing ⋅OH in situ, charting new path toward development green water‐treatment technologies. This review summarizes characteristics mechanisms ORR, focusing on basic principles latest progress situ efficient utilization modulation pathway, shedding light rational design catalysts, mechanistic exploration, practical applications water treatment. Finally, future developments challenges efficient, stable, large‐scale are discussed based achieving optimal regulation potential combine other

Electrochemical Dechlorination of Gaseous Trichloroethylene to Nonchlorinated Value-Added Products Using a Cu/Ni Alloy Electrode with a Gel Membrane Interface

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Trichloroethylene (TCE) is widely used in various industrial applications, leading to significant environmental and public health concerns due its toxicity persistence. Current nonthermal liquid-phase TCE treatment methods, including electrochemical processes, typically produce liquid byproducts that require additional separation steps, limiting their efficiency. To overcome these challenges, this study introduces an innovative approach for the direct conversion of gas into less harmful gaseous products, utilizing a Cu/Ni alloy 3D foam electrode integrated with poly(vinyl alcohol) (PVA)-sodium polyphosphate (SPP) gel membrane system. Our system demonstrated conductivity 0.05 S cm–1 phases at both half-cells, comparable existing polymeric membranes. Importantly, when no electrolyte was present, increased 0.09 cm–1, making setup highly suitable TCE. The removal efficiency evaluated by varying electrodeposition time modifying surface potassium hydroxide (KOH) cetyltrimethylammonium chloride (CTAC), resulting high rate 0.69 h–1. This enhanced performance attributed alloy's ability adsorb solubilize effectively under modified conditions. chromatography analysis definitively shows completely dechlorinated, about 75%. resulted ethene ethane 100% carbon recovery. gas-to-gas phase strategy eliminates need offering promising solution effective management chlorinated volatile organic compounds (CVOCs) reducing hazards.

Porous Mortars Incorporating Active Biochar from Olive Stone Waste and Recycled Masonry Aggregate: Effects of Accelerated Carbonation Curing

Materials, Год журнала: 2025, Номер 18(4), С. 904 - 904

Опубликована: Фев. 19, 2025

This study investigated the use of activated biochar derived from olive stone waste and recycled masonry aggregates in porous mortar mixtures assessed their behaviour under accelerated carbonation curing conditions. Three were produced, incorporating 0%, 5%, 10% by volume. The physical, chemical, mechanical properties mortars analysed, including compressive strength, flexural water absorption, porosity, CO2 capture capacity. Additionally, calorimetry tests performed on cement pastes with 0.5%, 1%, 3%, 15%, 20% to evaluate impact setting times ensure compatibility between cement. results showed that addition improved properties, particularly curing, whereas active (AcB) significantly enhanced strengths. Furthermore, incorporation boosted efficiency, mix showing up 147% higher uptake, compared a control. These findings suggest can be effectively utilised develop sustainable construction materials thereby contribute carbon sequestration reduction environmental impacts. research fills gaps current knowledge stones cement-base

Nano-biochar (NBC) is a promising tool for sustainable remediation of contaminants in aquatic environments. However, the presence ubiquitous ions and dissolved organic matter (DOM) can impact NBC aggregation, resulting reduced application efficacy potential ecological risks. Understanding regulating aggregation offers valuable insights its deployment. This study integrated batch experiments, theoretical models, Fourier transform ion cyclotron resonance-mass spectrometry (FTICR-MS), density functional theory (DFT) calculations to explore behaviors mechanisms with coexisting model DOM. kinetics followed classical Derjaguin-Landau-Verwey-Overbeek (DLVO) both NBC-ions NBC-ions-fulvic acid (FA) solutions, indicating that process controlled by Van der Waals forces electrostatic repulsion. Mono/di-valent electrolytes promoted whereas FA moderated it, higher molecular weight fractions exhibiting superior performance. Three-dimensional excitation-emission (3D-EEM) fluorescence spectra Parallel factor analysis (PARAFAC) analyses revealed HA-like substances, FA-like form complex ions, thereby moderating aggregation. FTICR-MS scans identified lignin substances aromatic structures as key components effectively reduce mono/di-valent electrolytes. DFT confirmed spontaneously complexes electrolytes, potentially research highlights strategies applications into behavior nanoparticles
