Our study focuses on the cubic Na₂XGaF₆ (X = In or Tl) double perovskite using density functional theory (DFT). We utilize the GGA and mBJ methods to account for exchange-correlation effects, with GGA employed to determine the ground state energy and optimal structural parameters, highlighting the stability of Na₂XGaF₆ (X = In or Tl) through its formation energy, tolerance factor, and octahedral tilting. Mechanical property evaluations indicate the brittle nature of the material. The bandgaps of Na₂InGaF₆ and Na₂TlGaF₆ double perovskites are found to be 2.6 eV and 5.84 eV, respectively, using the Tran-Blaha modified Becke-Johnson (TB-mBJ) potential for band structure and optical property analysis. Optical property assessments reveal significant polarization in the UV and visible spectrum, suggesting Na₂XGaF₆ as a promising candidate for photovoltaic applications. The thermoelectric performance of Na₂XGaF₆ (X = In, Tl) was evaluated using Boltzmann transport theory. Both compounds showed increasing electrical conductivity and power factor with temperature, while ZT slightly decreased. Na₂TlGaF₆ exhibited better thermal stability, making it more suitable for high-temperature thermoelectric applications.</div></div>","PeriodicalId":16811,"journal":{"name":"Journal of Physics and Chemistry of Solids","volume":"200 ","pages":"Article 112617"},"PeriodicalIF":4.3,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394381","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}

To this end, carbon materials containing ultra-thin carbon nanosheets were prepared by using ginkgo leaf as a carbon source and KCl as a stripping agent. The study found that the formation of ultra-thin carbon nanosheets depends on the structure of the biomass, and only Cl⁻ in KCl produces a stripping effect, independent of K⁺. The composition and structure of carbon materials are closely related to the mass of KCl, and different KCl mass can make carbon materials have different specific surface area and heteroatom content. When 12 g KCl was added, the prepared GCK-12 had the highest heteroatom content and medium specific surface area. Electrochemical test results show that the electrochemical performance of KCl-modified carbon materials is higher than that of unmodified carbon materials, indicating that ultra-thin carbon nanosheets provide more active sites for electrodes. Among them, GCK-12 has the best electrochemical performance, and the specific capacitance is 240 F g⁻¹ when the current density is 1 A g⁻¹. Above or below 12 g, the specific capacitance will be reduced. The symmetric supercapacitors assembled with GCK-12 have an energy density of up to 15 Wh kg⁻¹, which is superior to previously reported biomass carbon materials. By analyzing the relationship between the structure and electrochemical performance of GCK-12, it can be seen that increasing the heteroatom content is more beneficial to improve the electrochemical performance than increasing the specific surface area.

The results demonstrate that the introduction of CBz-PAI significantly enhances device efficiency by reducing interfacial charge recombination and improving solar energy harvesting, achieving an impressive power conversion efficiency (PCE) of 29.33 %. Furthermore, the structure demonstrates excellent thermal stability, thus underscoring the viability of tin-based PSC as a lead-free alternative.

Since organic dyes are poisonous, carcinogenic, and resistant to standard treatment techniques, they pose a serious threat to human health and the environment. Their continued presence in aquatic environments endangers human health by lowering water quality and upsetting aquatic life. The technique of photodegradation of dyes has the potential to significantly improve wastewater treatment's sustainability, economy, and efficiency, which would be extremely beneficial to the environment and public health. This comprehensive review focuses on the applications of rare earth-doped metal oxide nanoparticles as highly effective photocatalysts for dye degradation under UV–visible light irradiation. Rare earth dopants enhance visible light absorption, improve charge separation, and facilitate the generation of reactive oxygen species that drive the oxidative degradation of dye molecules. Synthesis methods including sol-gel, hydrothermal, and plant-mediated approaches for producing rare earth-doped nanoparticles are outlined. Key factors affecting the efficiency of photodegradation, including pH levels, catalyst concentration, temperature, duration, and initial dye concentration, are analyzed. The review elucidates the mechanisms underlying the pathways of photocatalytic dye degradation facilitated by rare earth dopants. A comparative assessment underscores the superior performance of rare earth-doped nanoparticles over their non-doped counterparts across a diverse array of dyes. These nanoparticles present a promising and sustainable avenue for efficient wastewater treatment by enhancing the photocatalytic breakdown of organic dye pollutants. In the broader context of sustainable chemical production, rare earth-doped nanoparticles not only contribute to environmental protection but also align with green chemistry principles by reducing the need for harsh chemicals and minimizing energy consumption during catalytic processes. Furthermore, their potential for integration into larger-scale chemical production systems paves the way for innovative materials that can drive eco-friendly industrial processes.
