Summary: In this study, the addition of highly active catalytic precursor TTONC greatly improved the hydrogen storage properties of MgH2. The TTONC-catalyzed MgH2 could absorb hydrogen at room temperature, and its onset dehydrogenation temperature was significantly lower than that of pristine MgH2. It also exhibited good cyclic stability with a high capacity retention rate after multiple hydrogen absorption-desorption cycles. The catalytic mechanism involved the in situ formation of TiH2, which acted as a hydrogen pump to enhance hydrogen diffusion, and the formation of stable CN layers on the surface of MgH2, which inhibited particle fragmentation and agglomeration.

Summary: In this work, a double design host and guest strategy is proposed to enhance the electrochemical properties of sulfur electrodes in sodium ion storage. The V2O3 adsorbent immobilizes sulfur species, while the selenium dopant improves the electronic conductivity and redox conversion of sulfur cathodes. The synergistic effect between the V2O3 adsorbent and selenium dopant inhibits the shuttle effect and improves the redox kinetics, resulting in greatly enhanced Na-ion storage properties of sulfur cathodes. The as-designed sulfur cathode exhibits excellent rate capability of 663 mA h g(-1) at 2.0 A g(-1) and exceptional cyclability of 405 mA h g(-1) over 700 cycles at 1.0 A g(-1).
