Searching for Pt‐like activity, stable and economic electrocatalysts that can function at various pH values for the hydrogen evolution reaction (HER) is under increasing interest for the scientific community as H2 is a very promising energy carrier with great potential development value for renewable energy conversion. Herein, a unique self‐supported heterostructure of RuO2‐RuP2/Ru on the N, P co‐doped...
Sandwich‐like MoS2@SnO2@C nanosheets are prepared by facile hydrothermal reactions. SnO2 nanosheets can attach to exfoliated MoS2 nanosheets to prevent restacking of adjacent MoS2 nanosheets, and carbon transformed from polyvinylpyrrolidone is coated on MoS2@SnO2, forming a sandwich structure to maintain cycling stability. As an anode for sodium‐ion batteries, the electrode greatly deliverers a high...
In article number 1703818, Ming Zhang and co‐workers prepare sandwich‐like MoS2@SnO2@C nanosheets by two‐step hydrothermal reactions, which show high capacities and excellent cycling stability for sodium/potassium ion batteries. This work may provide a new strategy to prepare other composites which can be applied to new kinds of rechargeable batteries.
To maximize the utilizing efficiency of cobalt (Co) and optimize its catalytic activity and stability, engineering of size and interfacial chemical properties, as well as controllable support are of ultimate importance. Here, the concept of coating uniform thin Co/N‐doped carbon layers into the mesopore surfaces of mesoporous silica is proposed for heterogeneous aqueous catalysis. To approach the...
In article number 1604045, by Ming Zhang, Guozhong Cao, and co‐workers, a phase‐separation strategy is developed to conveniently synthesize porous carbon nanotubes, which showed excellent rate capacity and cycling performance for sodium‐ion storage. This strategy may provide a route for the synthesis and application of core@shell or hollow materials in fields of energy and catalyst.
Porous carbon nanotubes (CNTs) are obtained by removing MoO2 nanoparticles from MoO2@C core@shell nanofibers which are synthesized by phase‐segregation via a single‐needle electrospinning method. The specific surface area of porous CNTs is 502.9 m2 g−1, and many oxygen‐containing functional groups (COH, CO) are present. As anodes for sodium‐ion batteries, the porous CNT electrode displays excellent...
