Description
Summary:Evidence by selected area diffraction patterns shows the successful preparation of large area (cm × cm) MoS<sub>2</sub>/graphene heterojunctions in coincidence of the MoS<sub>2</sub> and graphene hexagons (superlattice). The electrodes of MoS<sub>2</sub>/graphene in superlattice configuration show improved catalytic activity for H<sub>2</sub> and O<sub>2</sub> evolution with smaller overpotential of +0.34 V for the overall water splitting when compared with analogous MoS<sub>2</sub>/graphene heterojunction with random stacking.
