In article number 2301237, Shouyong Zhou, Junping Zhang, and co‐workers report the plant leaf‐inspired membrane separators based on natural attapulgite nanorods. The separators repel TFSI− ions but allow fast Li+ ions transport, showing ion‐selective transport behavior. So, the separators can guide uniform and directed Li deposition even at limited Li and high current...
Enhanced Hydrogen Evolution
MoS2 nanoflowers are successfully decorated on cobalt‐containing nitrogen‐doped carbon nanotubes to form dual‐active domains (Co‐NCNTs/MoS2). The coupling of featured domains optimizes the electronic structure and triggers the bifunctional effect to balance the Volmer step, thereby increasing the reaction step efficiency and leading to a high hydrogen evolution catalytic...

Superlattice Films
Work function difference induces spontaneous charge donation and band bending at the interfaces of superlattices, which causes optimization effects of modulation doping and energy filtering, leading to remarkably enhanced thermoelectric performances. This optimizing strategy is successfully elucidated in 1T′‐MoTe2/Bi2Te3 superlattice films. Meanwhile, the rational manipulation of...

The synergistic effect between boron doping and the modulated cobalt oxidation...
The development of adsorbents for Kr and Xe separation is essential to meet industrial demands and for energy conservation. Although a number of previous studies have focused on Xe‐selective adsorbents, stimuli‐responsive Xe/Kr‐selective adsorbents still remain underdeveloped. Herein, a Hofmann‐type framework Co(DABCO)[Ni(CN)4] (referred to as CoNi‐DAB; DABCO = 1,4‐diazabicyclo[2,2,2]octane) that...
Sodium‐ion batteries (SIBs) have attracted tremendous attention as promising low‐cost energy storage devices in future grid‐scale energy management applications. Bismuth is a promising anode for SIBs due to its high theoretical capacity (386 mAh g−1). Nevertheless, the huge volume variation of Bi anode during (de)sodiation processes can cause the pulverization of Bi particulates and rupture of solid...
