The Mg-Al LDH and MoS<sub>2</sub>/Mg-Al LDH composites were synthesized using hydrothermal method and applied for the removal of Congo Red dye from wastewater. The Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) confirms the successful formation of Mg-Al LDH hexagonal sheets on the surface of MoS<sub>2</sub> petals like structure, while Fourier Transform Infrared Spectroscopy (FTIR) was employed to investigate the functional group present in each sample. The adsorption efficiency of Mg-Al LDH and MoS<sub>2</sub>/Mg-Al LDH composites was 56.2 and 116.41 mg/g. Adsorption studies revealed that the MoS<sub>2</sub>/Mg-Al LDH composite exhibited excellent adsorption performance compared to MgAl LDH, with a maximum adsorption capacity of 116.41 mg/g. The adsorption behavior of Congo Red dye onto Mg-Al LDH and MoS<sub>2</sub>/Mg-Al composite was better described by the kinetic pseudo 2<sup>nd</sup> order model and conformed to the Langmuir isotherm model. The thermodynamics studies reveal that the uptake of Congo Red dye on MoS<sub>2</sub>/Mg-Al LDH nanocomposite followed a spontaneous and endothermic process. The superior adsorption capability is due to the electrostatic interaction between Congo Red dye with the MoS₂/Mg-Al LDH composite surface, as well as anion exchange between the Congo Red dye and the composite. These findings suggest that MoS<sub>2</sub>/Mg-Al LDH composite is emerging as a superior candidate for practical application in removing dye pollutants from wastewater.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"64 ","pages":"Article 106351"},"PeriodicalIF":5.7,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the protective performance will still decline in harsh desulfurized flue gas environments. The primary factors leading to the failure of EPN coating and the influence degree of each factor have not been thoroughly studied. In this paper, the anti-corrosion properties and failure mechanism of EPN coating in harsh desulfurized flue gas environments are studied based on experimental and artificial neural networks (ANN) analysis. The experimental results demonstrated the anti-corrosion properties of EPN coating are significantly influenced by 10 wt% H<sub>2</sub>SO<sub>4</sub> solution at 55 °C and cold-thermal shock at -60 – 140 °C. However, the sulfuric acid vapor environment with a pH of 0.2 – 0.5 at 55 °C has little effect on the corrosion protection performance of the EPN coating. Maybe the main reason is that the amine bond (C-N) in the EPN coatings is easily induced by acid-induced hydrolysis and the EPN coating is a brittle material and prone to brittle cracking due to alternating hot and cold. In addition, the contribution of each influencing factor to the failure of EPN coating is obtained by experiment and artificial neural networks: Sulfuric acid solution > Cold-thermal shock > Sulfuric acid vapor.

The following surface coatings were applied to H13 pins and tested: Nitrocarburizing, Duplex (plasma nitriding with multilayered CrAlN/CrTiN-based cathodic arc deposition), and Boronizing. To evaluate surface degradation, one specimen for each coating was tested in different conditions: pins before service and pins after 40,000 production cycles. The specimens were characterized by optical microscopy (OM), X-ray diffraction (XRD), scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDS), and mechanically by Vickers microhardness test. In conclusion, the duplex CrAlN/CrTiN-based coating deposited by a cathodic arc on a nitrided AISI H13 steel pin increased the mold service life within a 24 % minimum compared with that of the nitrocarburizing coating, which was the standard coating until present. The boronizing coating showed acceptable performance, but adjustments in the production process are needed to increase the service life of the H13 mold.
