It is shown that the siliconization of carbon felt without the use of a metallic catalyst is accompanied by a series of sequential and parallel redox reactions, including the formation of gaseous SiO, the formation of silicon dioxide (SiO2) in the free volume of the felt, and the growth of α-SiC nanowires on the resulting β-SiC fibers. It was established that the intermediate formation of silicon dioxide plays a key role in the growth of α-SiC nanowires. Silicon dioxide forms through the interaction of gaseous SiO with residual oxygen and through the local oxidation of the surface of β-SiC fibers in the silicon carbide felt. Subsequently, SiO2 is reduced by carbon and/or carbon monoxide to form SiC, which promotes nanowire growth and the formation of a cotton-like three-dimensional structure. The obtained results indicate that the formation of α-SiC nanowires in porous carbon matrices such as carbon felt is governed not only by the direct carbothermal conversion of silicon dioxide, but also by complex redox reactions occurring in the gas phase.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 9","pages":"1215 - 1223"},"PeriodicalIF":1.5,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023098","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}

The symmetric mode ν1(({text{A}}_{1}^{{{'}}})) of the nitrate ion ({text{NO}}_{3}^{ - }) was used as a structure-sensitive probe. It was found that the introduction of Mg(NO3)2 leads to a significant rearrangement of the phase behavior of the initial eutectic melt: at concentrations x ≥ 0.3, signs of glass formation and subsequent devitrification are observed, which are accompanied by exothermic effects during heating. Quantitative analysis of the parameters of the ν1(({text{A}}_{1}^{{{'}}})) oscillational mode revealed an increase in the amplitude of frequency fluctuations and an acceleration of oscillatory dephasing with increasing magnesium nitrate content. In this case, the contribution of heterogeneous broadening becomes dominant for intermediate compositions, indicating an increase in the structural heterogeneity of the system. It is shown that the addition of Mg2+ induces a transition from a simple eutectic melt to a structurally complex system with pronounced local heterogeneity and slowed relaxation dynamics.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 9","pages":"1298 - 1305"},"PeriodicalIF":1.5,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023021","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}

The synthesis route involving hydrogen reduction of the Cu/Ce0.75Zr0.25O2 precursor led to the formation of bimetallic Pt1–xCux particles with a solid-solution structure.
