Nanoscale zero-valent iron (nZVI)-based advanced oxidation processes (AOPs) are limited by the rapidly formed surface layer of iron (oxyhydr) oxides. This restriction can be broken by the simultaneous activation of H2O2 and peroxydisulfate (PDS, S2O8 2–) over sulfidated nanoscale ZVI (S-nZVI), which displayed a synergistic effect to alleviate the drawbacks of the oxidants used alone. In this work, a biochar-supported S-nZVI (noted as S-nZVI@BC) was employed to simultaneously activate PDS and H2O2 for methyl tert-butyl ether (MTBE) degradation, and the rate constant for S-nZVI@BC/Bi-ox (Bi-ox, bi-oxidant at 1:1 molar ratio of PDS and H2O2) was 3.7-, 4.5-, and 12.8-fold higher than that of nZVI@BC/Bi-ox, S-nZVI@BC/PDS, and S-nZVI@BC/H2O2. According to electron paramagnetic resonance (EPR), X-ray photoelectric spectroscopy (XPS), and in-situ oxygen detection analyses, oxygen vacancies were generated over the shell of S-nZVI@BC during PDS activation, and the oxygen vacancy-contained surface layers promoted H2O2 adsorption and dissociation to produce surface-bound ·OH (·OHads), thus significantly improving H2O2 utilization efficiency and accelerating MTBE degradation. These findings provide promising S-nZVI-based AOPs by combining H2O2 and peroxydisulfate activation for environmental remediation and bring insights for the creation of oxygen vacancy-containing materials for peroxide activation.

“…Şahin et al [ 24 , 25 ] systematically investigated various monomers, ratios of different monomers, and adjusted reaction processes. A series of polycarboxylate superplasticizers (PCEs) was synthesized using allyl alcohol-polyethylene glycol (APEG, EO = 45), acrylic acid (AA), maleic anhydride (MAL), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), and ammonium persulfate (APS) as raw materials.…”

The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects. The synthesis of PCE involves creating a novel macromolecular monomer with a controllable molecular mass, adjustable lipophilic, and hydrophilic moieties, as outlined in this study. This article reviews processes for synthesizing polycarboxylates and identifies the optimal method through orthogonal experiments to produce a modified polycarboxylate superplasticizer (PCE-P). The study investigated the effects of different PCE types and concentrations on the surface tension, fluidity, and ζ potential of cement paste. PCE-P, synthesized at room temperature, showed comparable performances in initial hydration and conversion rate in cement to PCE synthesized at high temperatures. PCE-P exhibited an increased slump but had a wider molecular weight distribution and longer main and side chains, leading to a 24.04% decrease in surface tension, indicating a good dispersibility.

“…Hence, ensuring quality control at various stages of the process is strongly recommended to maintain consistent separation performance throughout carbon capture and storage operations. As bio-based sorbents exhibit a limited adsorption capacity compared to other sorbents, their replacement or reactivation becomes necessary upon observing a decline in efficiency [ 121 , 122 ]. Additionally, the regeneration process hinges on the adsorption mechanism and mechanical stability of the material.…”

“…Additionally, the life cycle of bio-based sorbents warrants equal consideration, with life-cycle assessment (LCA) emerging as a crucial tool for estimating environmental impacts throughout the sorbent’s entire life cycle [ 125 ]. Strategies such as reusing spent bio-based sorbents as biofuel or catalysts for multiple applications, and employing renewable energy sources are highly sought after to enhance the efficiency and sustainability of carbon capture processes [ 121 ]. Conducting LCA and whole system analyses can further validate the value of emerging technologies in this field, providing insights into energy consumption, environmental impacts, and overall system efficiency.…”

Carbon dioxide (CO2) impacts the greenhouse effect significantly and results in global warming, prompting urgent attention to climate change concerns. In response, CO2 capture has emerged as a crucial process to capture carbon produced in industrial and power processes before its release into the atmosphere. The main aim of CO2 capture is to mitigate the emissions of greenhouse gas and reduce the anthropogenic impact on climate change. Biopolymer nanocomposites offer a promising avenue for CO2 capture due to their renewable nature. These composites consist of biopolymers derived from biological sources and nanofillers like nanoparticles and nanotubes, enhancing the properties of the composite. Various biopolymers like chitosan, cellulose, carrageenan, and others, possessing unique functional groups, can interact with CO2 molecules. Nanofillers are incorporated to improve mechanical, thermal, and sorption properties, with materials such as graphene, carbon nanotubes, and metallic nanoparticles enhancing surface area and porosity. The CO2 capture mechanism within biopolymer nanocomposites involves physical absorption, chemisorption, and physisorption, driven by functional groups like amino and hydroxyl groups in the biopolymer matrix. The integration of nanofillers further boosts CO2 adsorption capacity by increasing surface area and porosity. Numerous advanced materials, including biopolymeric derivatives like cellulose, alginate, and chitosan, are developed for CO2 capture technology, offering accessibility and cost-effectiveness. This semi-systematic literature review focuses on recent studies involving biopolymer-based materials for CO2 capture, providing an overview of composite materials enriched with nanomaterials, specifically based on cellulose, alginate, chitosan, and carrageenan; the choice of these biopolymers is dictated by the lack of a literature perspective focused on a currently relevant topic such as these biorenewable resources in the framework of carbon capture. The production and efficacy of biopolymer-based adsorbents and membranes are examined, shedding light on potential trends in global CO2 capture technology enhancement.
