The properties of 2D transition metal dichalcogenides are attracting a great deal of interest, and one of the reasons is their catalytic activity. In particular, better catalysts are needed to exploit the potential of water electrolysis – splitting water into its component elements – to provide sustainable energy storage. “MoS2 is one of the most
