Analysis of the samples by Raman, infrared, and X-ray photoelectron spectroscopy (Fe 2p_3/2 and Co 2p_3/2) revealed that the sintering temperature influences the distribution of cations in the spinel lattice. Specifically, increasing the sintering temperature leads to an increase in the inversion degree parameter (γ), which represents the fraction of Co ions residing in octahedral sites, driving the structure toward a fully inverted spinel. These results are in good agreement with those previously obtained by ⁵⁷Fe Mössbauer spectroscopy, X-ray diffraction, and X-ray absorption experiments on the same set of samples.

In this study, hydrogen absorbent alloys La₂Mg_1-xY_xNi₁₀Mn_0.5 (x = 0.1, 0.38) were produced by vacuum electric arc remelting. Crystal structure investigations revealed the presence of the LaNi₅ phase in both alloys and the formation of the (La, Mg)₂ Ni₇ phase in La₂Mg_0·62Y_0·38Ni₁₀Mn_0.5 alloy. The alloy with x = 0.38 demonstrated superior properties, including increased hydrogen absorption capacity (1.925 wt% vs 1.667 wt%) and improved hydrogenation kinetics which were related to the A₂B₇ superstructure phase. Electrochemical tests conducted at temperatures of 273, 283, 298, 313, and 338 K showed that an increasing temperature improved electrode surface activation. At room temperature, the retention rates of the discharge capacity after 50 charge and discharge cycles for the alloy electrodes (x = 0.1, 0.38) were 93.32 % and 96.56 % respectively, with maximum discharge capacities of 378.01 and 400.77 mAh/g. The high rate dischargeability (HRD) was evaluated, at different temperatures, demonstrating that the presence of a multiphase structure in the alloy with x = 0.38 created interphase boundaries, which reduced distortion, and network strain. These interphase boundaries also provided tunnels for hydrogen diffusion, improving activation and electrochemical stability. These findings suggest that partial substitution of Y for Mg in La–Mg–Ni based alloys offers a promising approach for developing high-performance hydrogen storage materials.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"348 ","pages":"Article 125340"},"PeriodicalIF":3.2,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, the various characterization techniques such as SAXS, WAXS, and <em>in situ</em> techniques to confirm the mesocrystal formation were discussed. We also addressed the major challenges such as controlled growth, stability, scalability, and reproducibility by highlighting their importance in advancing the synthesis methods. Additionally, a concise discussion on utilizing DFT and simulation to understand and model mesocrystals for optimizing their properties for specific applications has provided. Some of the key applications, including mesocrystals role in enhancing catalytic activity, electrical conductivity, and enabling terahertz generation, were discussed in detail. By consolidating the current understanding of mesocrystal formation and applications, this review focused to provide a foundation for future research, addressing the challenges and opportunities to utilize their potential in diverse scientific domains.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"347 ","pages":"Article 125331"},"PeriodicalIF":3.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
