要旨

It is well known that the electrochemical energy generation and storage performance of two-dimensional layered transition metal dichalcogenides (for example, MoS2 and WS2) strongly depend on the phase and properties of the electrode material. In this work, we report that 2H/1T phase coupling induced by Ru doping leads to improved electrochemical symmetric supercapacitor and hydrogen evolution reaction (HER) performance of a WS2 nanosheet electrode. XRD and Raman studies indicate that a 2H/1T multiphase emerges in WS2 nanosheets for the sample with 10 at% Ru (2H/1T-WS2-10) and other samples retain the parent 2H phase at a low Ru doping level. The 2H/1T-WS2-10 electrode with excellent catalytic activity delivers a 113 mV overpotential at a 10 mA cm−2 current density in 0.5 M H2SO4 electrolyte. Furthermore, the same electrode exhibits superior symmetric supercapacitor performance with high specific capacitance (664 F g−1@1 A g−1) and energy density (92 W h kg−1@1 A g−1) in 1 M Na2SO4 electrolyte. This work opens the way for the multifunctional use of doped WS2 for electrochemical energy conversion and storage applications.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
