Defect-rich MoS2 ultrathin nanosheets with additional active edge sites for enhanced electrocatalytic hydrogen evolution

Adv Mater. 2013 Oct 25;25(40):5807-13. doi: 10.1002/adma.201302685. Epub 2013 Aug 13.


Defect-rich MoS2 ultrathin nanosheets are synthesized on a gram scale for electrocatalytic hydrogen evolution. The novel defect-rich structure introduces additional active edge sites into the MoS2 ultrathin nanosheets, which significantly improves their electrocatalytic performance. Low onset overpotential and small Tafel slope, along with large cathodic current density and excellent durability, are all achieved for the novel hydrogen-evolution-reaction electrocatalyst.

Keywords: defects; electrocatalysis; hydrogen evolution; molybdenum disulfide; nanosheets.
