Though water electrolysis is effective in generating high-quality hydrogen gas,it requires effective electrocatalysts for hydrogen evolution reaction(HER).CoS_2 have been considered as a promising HER electrocatalyst because of its high ctalytic activity.However,the key limitation for CoS_2 nanomaterial as HER electrocatalyst is its poor stability,which may be due to the structural breakdown of CoS_2 nanostructure or the evolution of S during H_2 evolution in acid media.Coating porous carbon thin layer for protection from structural breakdown and evolution of S is a good way to improve catalytic stability.In addition,coating carbon layer can change electronic structure of CoS_2 for the moderated hydrogen adsorption energy,leading to enhanced catalytic activity.Here,CoS_2 yolk-shell spheres coated with carbon thin layers exhibit superior catalytic performance for HER with low overpotential,small Tafel slope,and excellent stability. 展开更多

CoS2 spheres were synthesized according to the previous study reported by Lifang Jiao and her collabora tots. The details are listed as follow ing: 1.65 mmol of COC12 6H20 was dissolved in absolute ethanol and then was transferred into a 40 mL Teflon lined stainless steel autoclave, then 4.1 mmol of sulfur powder was added into above solution. The Teflon lined stainless steel auto was subsequently stirred for 30 min. 展开更多

With increasing demands for clean and sustainable energy, the advantages of high power density, high efficiency, and long life expectancy have made supercapacitors one of the major emerging devices for electrochemical energy storage and power supply. However, one of the key challenges for SCs is their limited energy density, which has hindered their wider application in the field of energy storage. Despite significant progress has been achieved in the fabrication of high-energy density positive electrodes materials, negative electrode materials with high capacitance and a wide potential window are relatively less explored. In this review, we introduced some new negative electrode materials except for common carbon-based materials and what's more, based on our team's work recently, we put forward some new strategies to solve their inherent shortcoming as electrode material for SCs. 展开更多
