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.
