Recently vacancy-ordered double perovskite materials have attracted much consideration as promising entities in the domain of solar energy capture. Based on DFT calculation, optoelectronic and photocatalytic properties of Cs₂PtI₆ under strain effect were investigated. This Cs₂PtI₆ compound shows indirect band gap (Г–X) of 1.41 eV, and under applied tensile strain this band gap value widens to 1.998 eV. From optical properties calculation, the influence of strain is evident in the reduction of <i>R</i> (0) from 16.8% for unstrained Cs₂PtI₆ to 12.5%. Notably, the obtained loss energy within the visible range remains obviously small (below 0.1) in the energy spectrum below 3 eV, showcasing minimal energy loss in this material under tensile strain. Furthermore, this investigation establishes the viability of 6% applied strain to highlighting Cs₂PtI₆ as a candidate for solar water splitting, enhancing its efficacy in H₂O oxidation for pH levels ranging from 6 to 11 compared to the unstrained form. Moreover, the application of 6% tensile strain significantly improves the efficiency of Cs₂PtI₆ as a photocatalyst for converting CO₂ into valuable compounds like C₂H₄, CH₃COOH, CH₄, and graphite C, particularly notable at pH = 7. These findings highlight the efficiency of strain engineering in advancing the performance of Cs₂PtI₆ for solar-driven chemical transformations, representing a significant stride in sustainable energy research.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7307 - 7320"},"PeriodicalIF":3.5,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930011","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}

The influence of Al content on the phase composition, microstructure, tribological behavior, electrochemical performance, and mechanical properties of the coatings was comprehensively examined. The findings reveal that the phase structure of the HEA coatings transitions from a single FCC phase (<i>x</i> = 0, 0.3) to a dual FCC + BCC phase (<i>x</i> = 0.5, 0.7) and ultimately to a single BCC phase (<i>x</i> = 1.0). With increasing Al content, the microstructure evolves from columnar to equiaxed crystals, accompanied by progressive grain refinement. This grain refinement enhances the hardness of the coatings, which correlates positively with improved tribological properties. At <i>x</i> = 1.0, the coating demonstrates the lowest wear rate. Conversely, the corrosion resistance decreases as Al content increases, with the minimum corrosion current density observed at <i>x</i> = 0 (22.491 μA·cm⁻²). Furthermore, the tensile properties improve initially and then deteriorate with increasing Al content, achieving optimal mechanical performance at <i>x</i> = 0.5.

The mechanical behavior of Al-27%Si hypereutectic Al-Si alloy in high-temperature stress–strain testing was studied. The results showed that the overall content of the liquid film during the solidification process affects the mechanical properties of the alloy; the alloy exhibited viscoelasticity in a high solid fraction state and viscoplasticity in a low solid fraction state. At the same time, a Si-liquid film-Si structure was constructed to simulate the intergranular liquid film structure of hypereutectic Al-Si alloy in the final stage of solidification. The stress variation characteristics of the intergranular liquid film showed that the smaller the liquid film thickness, the stronger the interaction force between Si wafers, which is not conducive to improving the liquid film fluidity. In addition, the fracture morphology of the tensile fracture was observed, and it was found that under the condition of thick liquid film, the flowability of the residual liquid phase was better, making it easier to feed for hot tearing. Finally, CFD simulation technology was used to study the mechanism of the effect of a single factor of liquid film characteristics on hot tearing.
