Abstract

On page 6207, Y. Zhang, Z. Liu and co-workers describe morphologically engineered 2D-MoS2 for the facilitation of efficient hydrogen evolution reaction. Two pathways to achieve such a purpose are highlighted, either by non-equilibrium growth of MoS2 dendrites or by high-density nucleation of MoS2 nanoflakes directly on the electrode materials. Future research directions are also proposed and discussed to further enhance the efficiency of such unique catalysts.
