However, to be effective at high temperatures in the presence of acid, the mechanical and conductive properties of the material must be stable and no critical increase in gas permeability is required. This work proposes an approach to improve the properties of PBI-O-PhT-based materials by combining two previously known methods: covalent crosslinking with silane (3-bromopropyl)trimethoxysilane (Si<img>Br) and doping with silicon oxide (SiO₂), including grafted imidazolinpropyl groups (SiO₂Im). The silanol cross-linked samples exhibited higher stability when tested with Fenton's reagent and retained their morphological integrity even after 360 h of testing. The study shows that covalent crosslinking improves the stability of dopant particles in the membrane matrix and prevents their leaching during acid treatment. Additionally, the incorporation of silicon oxides enhances the proton conductivity of samples with covalent cross-linking and reduces gas permeability compared to the original PBI membrane. Proton conductivity of the covalent cross-linked samples reaches 50 and 55 mS·cm⁻¹ at oxide contents of 5 wt% SiO₂Im and 10 wt% SiO₂, respectively.</p></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"414 ","pages":"Article 116644"},"PeriodicalIF":3.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interstitial water within the structure of PBAs has been a primary cause of structural instability, performance degradation, and a major barrier to their widespread application. Herein, the incorporation of large-radius ions (K⁺, Ba²⁺, Ca²⁺, La³⁺) into the structure of iron-based Prussian Blue via ball milling and its impact on the structure and properties of the material are investigated. The ions (Ba²⁺, Ca²⁺, La³⁺) readily react with (C₂O₄)²⁻ during the synthesis process to form oxalate impurities.

They correspond to bound states of fundamental polar vibrations of oxygen ions of O₆ oxygen octahedra of A₁- and E-type symmetry and arise only due to strong anharmonicity of vibrations. It has been shown that the effects of strong anharmonicity manifest themselves most clearly for librational vibrations of O₆ oxygen octahedra as a whole. The Raman band (<em>ν</em> = 76 cm⁻¹, <em>T</em> = 293 K) corresponds to the librational vibrations of O₆ oxygen octahedra. Solid solution of the composition Li_0.12Na_0.88Ta_0.5Nb_0.5O₃ is characterized by the most disordered sublattice of niobium and tantalum. The band of this ceramics composition with increasing temperature experiences a strong broadening and a decrease in intensity, compared to other bands of the spectrum; at temperatures above 650 K the band is completely blurred into the wing of the Rayleigh band. Note that all this happens in the pre-transition region of the diffuse superionic phase transition in the range ≈670-730 K. This fact indicates the dynamic disordering of the sublattice of O₆ oxygen octahedra. Dynamic disordering accompanies the phase transition to the superionic state in the Li_0.12Na_0.88Ta_0.5Nb_0.5O₃ solid solution; therefore, the activation energy of ionic conductivity decreases sharply. In this case, the disorder of cations in the sublattice of niobium and tantalum is the greatest precisely at y = 0.5. It facilitates the superionic phase transition. Dynamic disordering of the O₆ oxygen octahedra sublattice as a whole was not detected for other compositions of Li_0.12Na_0.88Ta_yNb_1-yO₃ solid solutions with y &lt; 0.5 in the studied temperature range. A phase transition is observed (through some intermediate metastable state) to a state with high ionic conductivity for lithium at a relatively high value of activation energy for conductivity before and after the transition for these compositions. Thus, approaches have been developed to predict the possibility of superionic conductivity in perovskite oxygen-polyhedral structures with the general formula Li_0.12Na_0.88Ta_yNb_1-yO₃ based on studying the concentration and temperature dependences of first- and second-order Raman spectra.
