The slow redox kinetics during cycling process and the serious shuttle effect caused by the solubility of lithium polysulfides (LiPSs) dramatically hinder the practical application of Li‐S batteries. Herein, a facile and scalable spray‐drying strategy is presented to construct conductive polar Mo2C quantum dots‐decorated carbon nanotube (CNT) networks (MCN) as an efficient absorbent and electrocatalyst...
It is still challenging to develop high‐efficiency and low‐cost non‐noble metal‐based electrocatalysts for hydrogen evolution reaction (HER) in pH‐universal electrolytes. Herein, hierarchically porous W‐doped CoP nanoflake arrays on carbon cloth (W‐CoP NAs/CC) are synthesized via facile liquid‐phase reactions and a subsequent phosphorization process. The W‐CoP NAs/CC hybrid can be directly employed...
As anodes of Li‐ion batteries, copper oxides (CuO) have a high theoretical specific capacity (674 mA h g−1) but own poor cyclic stability owing to the large volume expansion and low conductivity in charges/discharges. Incorporating reduced graphene oxide (rGO) into CuO anodes with conventional methods fails to build robust interaction between rGO and CuO to efficiently improve the overall anode performance...
In article number 1702667, Jie Xiong, Weidong He, and co‐workers synthesize high‐performance Cu2O/CuO/rGO through a facile single‐step hydrothermal method and employ it as an anode of a lithium‐ion battery, delivering remarkable energy capacity, rate capacity and thermal stability. In the cover, the two “magic” hands represent the 3D hierarchical network of rGO. The robust “magic” network mitigates...
Monolayer MoS2 is synthesized on hexagonal boron nitride (h‐BN) flakes with a simple, high‐yield method. Monolayer MoS2 on h‐BN exhibits improved optical quality. Combining the theoretical and experimental analysis, it is concluded that the enhanced photoluminescence and Raman intensities of monolayer MoS2 probably originate from the relatively weak doping effect from the h‐BN substrate rather than...
