Paper Abstract

We synthesized molybdenum disulfide (MoS2) nanostructures and investigated their electrochemical activity for driving the hydrogen evolution activity as well as their photoelectrochemical activity for the water splitting reaction. MoS2 nanoparticles were made using a reverse micelle encapsulation method and exhibit quantum confinement of the indirect band gap up to 1.8 eV. A MoS2 double-gyroid bi-continuous structure was made using an evaporation induced self assembly method. Both nanostructures exhibit improved activity for the hydrogen evolution reaction versus bulk MoS2. Photoelectrochemical activity was also observed in both nanostructures.
