Gold Nanoclusters Grown on MoS(2) Nanosheets by Pulsed Laser Deposition: An Enhanced Hydrogen Evolution Reaction

Au nanoparticles were decorated on a 2H MoS(2) surface to form an Au/MoS(2) composite by pulse laser deposition. Improved HER activity of Au/MoS(2) is evidenced by a positively shifted overpotential (−77 mV) at a current density of −10 mA cm(−2) compared with pure MoS(2) nanosheets. Experimental evi...

description Au nanoparticles were decorated on a 2H MoS(2) surface to form an Au/MoS(2) composite by pulse laser deposition. Improved HER activity of Au/MoS(2) is evidenced by a positively shifted overpotential (−77 mV) at a current density of −10 mA cm(−2) compared with pure MoS(2) nanosheets. Experimental evidence shows that the interface between Au and MoS(2) provides more sites to combine protons to form an active H atom. The density functional theory calculations found that new Au active sites on the Au and MoS(2) interface with improved conductivity of the whole system are essential for enhancing HER activity of Au/MoS(2).
