Abstract

A series of superconducting samples including pure Bi₂Sr₂Ca₂C₃O₁₀ (BSCCO), Pb-doped BSCCO (Bi_1.35Pb_0.65Sr₂Ca₂Cu₃O₁₀), Mg-doped BSCCO (Bi_1.65Mg_0.35Sr₂Ca₂Cu₃O₁₀), and optimally co-doped Pb-Mg-BSCCO with an optimal formula of BiPb_0.65Mg_0.35Sr₂Ca₂Cu₃O₁₀ (108K superconductor) were carefully synthesized and optimized with a maximum ratio of incorporated lead and magnesium, achieving both quality of structural features and an improved T_c offset of 108 K. The optimized porous sample was well characterized via x-ray diffraction, Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), and three-dimensional atomic force microscopy (3D-AFM). In addition, the Brunauer–Emmett–Teller (BET) specific surface area was estimated at 11.9 m²g⁻¹. Porous Mg-doped BPSCCO exhibited high performance efficiency for H₂ storage, recording maximum H₂ uptake of 5.92 wt.% at a temperature of 270°C and pressure of 14 bar. A mechanism of loaded hydrogen was proposed. Magnesium and lead incorporated in 2223-BPSCCO were suggested to play a vital role in hydrogen storage as Mg hydride and Pb as plumbane.

多孔掺镁 2223-BPSCCO 超导瞬变铅垂体作为储氢装置的新应用

我们精心合成并优化了一系列超导样品，包括纯 Bi2Sr2Ca2Cu3O10（BSCCO）、掺铅 BSCCO（Bi1.35Pb0.65Sr2Ca2Cu3O10）、掺镁 BSCCO（Bi1.65Mg0.35Sr2Ca2Cu3O10）以及最佳共掺 Pb-Mg-BSCCO（最佳配方为 BiPb0.65Mg0.35Sr2Ca2Cu3O10，108K 超导体）。通过 X 射线衍射、拉曼光谱、场发射扫描电子显微镜（FE-SEM）和三维原子力显微镜（3D-AFM）对优化后的多孔样品进行了表征。此外，布鲁纳-埃美特-泰勒（BET）比表面积估计为 11.9 m2g-1。掺杂镁的多孔 BPSCCO 具有很高的氢气存储效率，在温度为 270°C 和压力为 14 巴时，最大氢气吸收率为 5.92 wt.%。提出了负载氢的机理。研究表明，2223-BPSCCO 中的镁和铅作为氢化镁和铅作为铅垂体在储氢中发挥了重要作用。

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
