The electrochemical reduction of CO<sub>2</sub> (CO<sub>2</sub>RR) offers a promising strategy to convert CO<sub>2</sub> into valuable products such as ethylene (C<sub>2</sub>H<sub>4</sub>), methane (CH<sub>4</sub>), carbon monoxide (CO), methanol (CH<sub>3</sub>OH), and ethanol (C<sub>2</sub>H<sub>6</sub>O). In this study, we report the integration of Cu-based metal-organic framework (MOF) electrocatalysts into gas diffusion layers (GDLs) to enhance CO<sub>2</sub>RR performance. Electrocatalysts, specifically Cu/ZnO-UiO66 and Cu/ZnO-MDC, were deposited onto GDLs using an air-spraying technique, ensuring a homogeneous distribution of active metals across the substrate. Comprehensive characterisation of the modified GDLs was performed using field-emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (FESEM-EDX), X-ray diffraction (XRD), and tensiometer to assess surface morphology, textural properties, and phase composition, respectively. The deposition process resulted in a notable increase in hydrophilicity compared to pristine GDLs, as indicated by reduced contact angles. CO<sub>2</sub>RR experiments conducted in a liquid flow system demonstrated that the Cu/ZnO-UiO66-based GDL achieved FEs of 40 % for CO production, 6 % for CH<sub>4</sub>, and 3 % for C<sub>2</sub>H<sub>4</sub>, at a cathodic potential of −1.0 V vs RHE. In contrast, the Cu/ZnO-MDC-based GDL delivered FEs of 17 % for CO and 10 % C<sub>2</sub>H<sub>4</sub>, as well as 2 % for CH<sub>4</sub>, under similar conditions. These findings underscore the potential of Cu-based MOF electrocatalysts in enhancing CO<sub>2</sub> reduction processes. However, further optimization of the catalyst properties and deposition techniques is necessary to improve performance and selectivity, paving the way for more efficient CO<sub>2</sub> conversion technology.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101184"},"PeriodicalIF":7.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photocatalytic nanoparticles offer potential advantages due to their high reactivity under UV light, which can degrade complex organic molecules through oxidation processes, whereas nZVI is recognized for its reductive and environmentally friendly capabilities. Here, the interaction dynamics of these NPs with MB was investigated. Briefly, the adsorption rates, degradation efficiency, and the influence of physical and chemical properties on the removal of MB was studied. The interaction mechanism was elucidated by UV–Vis, Dynamic Light Scattering (DLS), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR). The results showed while nZVI is an effective reducing adsorbent, it struggles with the stable structure of MB. In a similar response to nZVI, MgO demonstrated superior adsorption capabilities compared to other NPs by over 4 mg/g MB adsorption. The findings suggest that the choice between photocatalytic NPs and nZVI should consider the specific nature of the contaminants and the desired pathway (oxidative vs. reductive) for their removal.

Owing to the impacts of climate and the environment, the slope of the open channel section of expansive soil has repeatedly experienced sliding damage. After silty sand was used as a replacement material for treatment, the slope still experienced sliding damage after a period of operation. Therefore, this study systematically explored the mechanical properties and physical mechanisms of silty sand under dry-wet-freeze-thaw (DWFT) cycles through direct shear, compression, SEM, electron microscopy, and triaxial tests. The research results show that: (1) As the number of DWFT cycles increases, the cohesion and internal friction angle of silty sand decrease exponentially, with maximum deterioration degrees of 4.61 % and 2.52 %, respectively, while the compression coefficient increases slightly. The influence of cycling on the shear and compression characteristics of silty sand is limited, and it still exhibits low compressibility. (2) Microscopic analysis indicates that the skeleton of silty sand is mainly composed of sand grains, with fine particles and clay mineral aggregates filling the pores. Cycling leads to an increase in internal pores within weakly cemented aggregates and fluctuations in microscopic porosity, but the particle skeleton remains relatively stable. (3) Macro- and micro-scale tests reveal that DWFT cycles have a minor impact on the mechanical properties of silty sand, thus it suffices to study the stress-strain relationship of uncycled samples. Triaxial tests show that silty sand exhibits a hardening stress-strain relationship with only shear contraction at low compaction degrees. As compaction increases, softening intensifies, and volumetric deformation initially involves shear contraction followed by shear dilation. With increasing confining pressure, softening diminishes, and shear contraction enhances. (4) Model validation: Parameters for the model are derived from the triaxial test results, with the stress-strain-bulk strain relationship of silty sand predicted through substitution into the model. A comparison between experimental values and model predictions indicates that the constitutive model related to sandy soil effectively simulates the stress-strain and bulk strain relationships of silty sand, adequately reflecting the variations in mechanical properties. However, several issues remain that require improvement.

The absorption characteristics of SAMs are governed by three fundamental parameters: the chemical nature of hydrophilic functional groups, the 3D network architecture, and the cross-linking density.

The algae were obtained from a photobioreactor designed for atmospheric CO<sub>2</sub> capture. Several analytical methods were employed for the characterization of these sources, including thermogravimetric analysis (TGA) in air and nitrogen, microscale combustion calorimetry (MCC), and a combined thermogravimetric analysis with mass spectrometry (MS) and Fourier-transform infrared spectroscopy (FTIR). The waste morphology and composition were examined using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR). Thermogravimetric results indicated that adding Cho to railway sleeper waste improved combustibility, with the most favorable outcomes at a 15 % Cho mixture. MCC analysis revealed that the most efficient energy-recovery mixtures were 30Cho-P, 30Cho-T, 15Cho-G, 30Cho-C, and 45Cho-A. Furthermore, TG-MS-FTIR analysis showed that CO<sub>2</sub> was the dominant emission, with SO<sub>2</sub> present in tire-based mixtures and NO/NO<sub>2</sub> in textiles ones. FTIR spectra confirmed the identification of ionic fragments in the decomposition gases, further supporting the findings on gaseous emissions from the binary waste mixtures.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101175"},"PeriodicalIF":7.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
