Au nanoparticle-modified MoS2 nanosheet-based photoelectrochemical cells for water splitting.

ABSTRACT

The surface plasmon resonance of Au nanoparticle on MoS2 nanosheet is successfully measured by the electron energy-loss spectroscopy. Furthermore, Au-MoS2 composite is developed as the photoanode material in the photo-electronchemical cell (PEC) for water splitting. Compared to the pure MoS2 -based PEC, Au-MoS2 based PEC shows the enhanced performance in the photocatalytic water splitting.
