Title: Ultrasmall Cu7 S4 @MoS2 Hetero-Nanoframes with Abundant Active Edge Sites for Ultrahigh-Performance Hydrogen Evolution. Author: Xu J, Cui J, Guo C, Zhao Z, Jiang R, Xu S, Zhuang Z, Huang Y, Wang L, Li Y. Journal: Angew Chem Int Ed Engl; 2016 May 23; 55(22):6502-5. PubMed ID: 27094459. Abstract: Increasing the active edge sites of molybdenum disulfide (MoS2 ) is an efficient strategy to improve the overall activity of MoS2 for the hydrogen-evolution reaction (HER). Herein, we report a strategy to synthesize the ultrasmall donut-shaped Cu7 S4 @MoS2 hetero-nanoframes with abundant active MoS2 edge sites as alternatives to platinum (Pt) as efficient HER electrocatalysts. These nanoframes demonstrate an ultrahigh activity with 200 mA cm(-2) current density at only 206 mV overpotential using a carbon-rod counter electrode. The finding may provide guidelines for the design and synthesis of efficient and non-precious chalcogenide nanoframe catalysts.[Abstract] [Full Text] [Related] [New Search]
