The hierarchical structure of molybdenum disulfide nanosheet arrays derived from nickel-cobalt layered double hydroxide/carbon cloth, allows more MoS2 active sites to be exposed for good hydrogen evolution reaction activity.
The hierarchical structure of molybdenum disulfide (MoS2) nanosheet arrays stemmed from nickel-cobalt layered double hydroxide (NiCo-LDH)/carbon cloth was prepared by growing the MoS2 nanosheet arrays onto the NiCo-LDH template which was pre-deposited onto the carbon cloth substrate. In this electrode configuration, carbon cloth is the three dimensional and conductive skeleton; NiCo-LDH nanosheets, as the template, ensure the oriented growth of MoS2 nanosheet arrays. Therefore, more MoS2 active sites are exposed and the catalyst exhibits good hydrogen evolution reaction activity.
