Novel Application of Porous Mg-Doped 2223-BPSCCO Superconductor-Induced Metastable Plumbane as Hydrogen Storage
A series of superconducting samples including pure Bi2Sr2Ca2C3O10 (BSCCO), Pb-doped BSCCO (Bi1.35Pb0.65Sr2Ca2Cu3O10), Mg-doped BSCCO (Bi1.65Mg0.35Sr2Ca2Cu3O10), and optimally co-doped Pb-Mg-BSCCO with an optimal formula of BiPb0.65Mg0.35Sr2Ca2Cu3O10 (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 Tc 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.
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.
