The quest for environmentally friendly and highly effective energy storage solutions has raised awareness of heteroatom-rich carbon materials as potential active cathodes for zinc-ion hybrid supercapacitors (ZIHSC). These substances offer a distinctive combination of elevated electrical conductivity, large surface area, and abundant electroactive sites because of the addition of heteroatoms like phosphorus, sulfur, and nitrogen. Doping with heteroatoms improves the hydrophilicity of the carbon material, enhancing the electrolyte accessibility and ion transport. Magnified cycling stability of ZIHSC is observed due to the strong bonding between heteroatoms and carbon, which can mitigate the structural degradation during repeated charge–discharge cycles. Heteroatom-rich carbon-based cathodes for ZIHSCs face challenges such as maintaining structural stability and preventing heteroatom leaching during repeated charge–discharge cycles, which can degrade performance. To address these challenges, researchers are developing advanced synthesis methods to achieve uniform doping and enhance structural stability, while also exploring protective coatings and binder materials to prevent heteroatom leaching and improve electrode–electrolyte interface stability. This review explains the latest progress, highlights the ongoing challenges, and provides insights into future research directions for heteroatom-rich carbon materials in hybrid supercapacitor applications.

Rust preventives (RPs) are often employed to protect carbon steel from atmospheric corrosion during manufacture, storage, and/or transportation. In this work, commercial oil-based RPs containing graphene and PREFER were tested as protective layers on SAE 1006 steel. PREFER is a bi-dimensional/layered zeolite formed by ordered ferrierite layers. X-ray diffraction analysis confirmed formation of the zeolite. Electrochemical impedance spectroscopy results showed that the presence of graphene and PREFER in the RP provided ten-fold higher resistance than the RP without additives, after 22 h of immersion in 0.1 mol L−1 NaCl. On the other hand, the RP containing delaminated PREFER provided no corrosion protection, confirming the bidimensional effect of the filler in the oil-based RP. Salt spray and humidity test results corroborated the electrochemistry data. The steel sample coated with RP_PREFER-CTAB presented red corrosion on less than 10 % of the surface. The sample coated with RP_G did not present corrosion and the coating was easier to remove using alkaline cleaning solution, indicating its superiority as a temporary coating, compared to RP_PREFER-CTAB and the oil containing only sulfonate inhibitor.

To inhibit the corrosion of carbon steel, epoxy polymer coatings were developed using cellulose nanofibers (CNF) and the corrosion inhibitors sodium nitrate (SN) and sodium oleate (SO). The synergistic effects of SN and SO were confirmed by measuring the polarization curves of bare carbon steel in a corrosive solution, which demonstrated the effectiveness of a first action by SN being followed by a second action by SO. In order to control the release rates for the corrosion inhibitors from polymer coatings, the addition of CNF in the polymer was effective. The optimum combination of SN, SO and CNF in the polymer coatings was 8% of SN in the first layer, then 8% and 0.5% of SO and CNF, respectively, in the second layer, which resulted in excellent self-healing properties. The controlled release for the synergistic effect of the corrosion inhibitors allowed them to generate a healing film on the damaged portions of carbon steel.

The present study aims to shed light onto the influence of structural design on the overall properties of a series of aliphatic–aromatic CN-based copoly(ether-imide)s, with emphasis on energy storage performance, with the support provided by selected benchmarks. To boost the energy storage capability of the free-standing films made therefrom, three molar ratios of a CN-aromatic hard segment and a Jeffamine-based soft component were used. Thus, through different chemical strategies and their synergism, the films morphology and their physico-chemical properties like wetting, optical, mechanical, thermal, dielectric and, particularly breakdown strength and energy storage were modulated. The results showed high thermal stability, single glass transition temperatures, good mechanical properties, and relative low dielectric constants of the copolymers. The absence of crystallization demonstrated the amorphous nature of the films due to the good interpenetration of soft and hard components, although some phase separations were observed in some copolymers with no clearly defined boundaries. Due to the balanced thermal stability, dielectric behavior, mechanical features, and film processing ability, these copoly(ether-imide)s display potential applications in high-temperature energy storage field, reaching breakdown strength and energy storage density values up to 459 kV/mm and 2.70 J/cm3, respectively.

The green synthesis of silver nanoparticles (Ag NPs) on textiles using natural extracts is emerging as an innovative, eco-friendly approach for enhancing both antibacterial properties and dyeing performance. This study introduces a novel in-situ method for synthesizing Ag NPs directly on polyamide (PA) fabrics, utilizing Scrophularia striata Boiss extract (SBE) as a natural dye and reducing agent. UV–visible spectroscopy and dynamic light scattering (DLS) were used to characterize the synthesis process and determine the average particle size of Ag NPs. The data showed particle sizes of 62.5 nm and 56.1 nm when using flower and stem extracts, respectively. Surface morphology findings from scanning electron microscopy (SEM) and corresponding diffraction peaks in X-ray diffraction (XRD) confirmed the in-situ formation of Ag NPs on the surface of PA fabric. Fabrics dyed with SBE and Ag NPs exhibited higher color strength (K/S values of 4.1 and 5.6 for flower and stem, respectively), showing 64 % and 100 % increases compared to samples without silver. Additionally, PA fabrics exhibited 100 % inhibition against E. coli and S. aureus bacteria. After 10 washing cycles, antibacterial activity was maintained at 88 % and 85 % for the stem extract and 83 % and 79 % for the flower extract. This research highlights the novel integration of natural dye and nanoparticle synthesis, providing a sustainable route for multifunctional textile development.

The electrochemical reduction of CO2 (CO2RR) presents a dual benefit: it helps mitigate environmental pollution while producing valuable multi-carbon (C2+) chemicals and storing renewable energy in chemical fuels. However, there is an urgent need for efficient electrocatalysts that can selectively increase the production of ethylene and C2+ products for the wide-scale implementation of CO2RR. Herein, we have facilely synthesized porous micro-caged oxide-derived copper oxide (OD-Cu MC) using a one-pot hydrothermal approach followed by air-annealing at 350 °C. The resulting electrocatalyst exhibited excellent performance for ethylene (C2H4) production, achieving a faradaic efficiency (FE) of 44.8 % for C2H4 and cumulative FE of 73.1 % for C2+ products at current density (ID) of 300 mA cm−2. At an ID of 400 mA cm−2, OD-Cu MC demonstrated a turnover frequency (TOF) of 0.012 s−1 for ethylene, which is 7.8 times higher than the TOF observed for commercially available copper oxide (CuO-CM). Moreover, at an ID of 300 mA cm−2, OD-Cu MC achieved a single-pass CO2 conversion (SPCC) of 35.2 % and a half-cell energy efficiency of 15.6 % for C2+ products. The catalyst also showed good stability, maintaining its performance for over 4 h at an ID of 200 mA cm−2. This straightforward synthesis approach opens new avenues for enhancing C2+ product selectivity in CO2RR.

Semiconducting metal oxides, such as zinc oxide (ZnO), are gaining recognition for thermoelectric applications due to their temperature stability, availability, eco-friendliness, and cost-effectiveness. However, ZnO faces challenges in achieving high ZT value due to its low carrier concentration and high thermal conductivity. Traditional methods, like doping and defect engineering, have shown limited success in overcoming these challenges. In this study, we introduce a unique superlattice structure with a phase-composite composition that significantly decreases thermal conductivity through enhanced phonon scattering while maintaining the power factor by inducing new resonant conducting states near the mobility edge. By optimizing nanolayer thickness and doping concentration, we achieved a remarkable power factor of 14.6 μW cm−1 K−2 and reduced thermal conductivity to ∼1.97 W m−1 K−1 at room temperature in samples with 6 nm-thick ZnO nanolayers fabricated at 100 °C. This leads to a ZT value of ∼0.22 at 300 K, the highest among metal oxide thermoelectric materials at low temperatures, which further increases to ∼0.55 at 510 K. These findings demonstrate the potential of hybrid superlattices for efficient low-temperature thermoelectric applications.

These findings demonstrate the potential of hybrid superlattices for efficient low-temperature thermoelectric applications.</div></div>","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"145 ","pages":"Pages 659-667"},"PeriodicalIF":5.9,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
We successfully synthesised ZIF-8 using the solvothermal method at room temperature to study CO2 adsorption storage at 273 and 298 K up to 35 bar. Characterisation methods such as BET, SEM-EDS, XRD, and TGA were used to measure the physical and composition properties of ZIF-8. Grand canonical Monte Carlo (GCMC) simulation was conducted to compare with experimental data and get inside of the CO2 adsorption mechanism by calculating the isosteric heat and its fluid–fluid and solid–fluid contributions. The second was also split into fluid–solid atom contributions to understand in detail the interaction between CO2 and ZIF-8. The analyses revealed that there are three main stages during the CO2 adsorption gas–solid atom contributions, developing, pore-filling and densification. During the developing and pore-filling stages the largest fluid–solid atom contribution to the isosteric heat is CO2-C2 interactions, indicating that the CO2 is adsorbed close to the hexagonal windows of the ZIF-8 structure, while during the densification stage the largest contribution is CO2-N interactions. Where C2 and N refers to C-atom and N-atom, respectively in NCH group of the solid framework. This is because CO2 changes its orientation to be able to accommodate more molecules in the pore cavity. This work provides a better understanding of the adsorption mechanism of CO2 on ZIF-8 and shows how molecular simulation can be used to improve the understanding gas adsorption storage on metal–organic frameworks.
