dc.description.abstractA new composite material consisting of 0D MoS<inf>2</inf> nanodots and 3D MoS<inf>2</inf> nano-flowers grown on porous reduced graphene oxide (P-rGO) was synthesized via a two-step process. The P-rGO with a surface area of 759 m<sup>2</sup> g<sup>−1</sup> was obtained by CO<inf>2</inf> activation of reduced graphene oxide (rGO) at 800 °C. MoS<inf>2</inf> was then grown on the P-rGO under hydrothermal conditions. Compared to the nonactivated rGO, P-rGO has functional pores for deposition of MoS<inf>2</inf> nanodots and less charge transfer resistance, which can provide more active sites for hydrogen generation, thus leading to the improved activity of (0D/3D) MoS<inf>2</inf>/P-rGO in hydrogen evolution reaction (HER). The overpotential of (0D/3D) MoS<inf>2</inf>/P-rGO was only ∼150 mV vs. RHE, and the corresponding Tafel slope was ∼56 mV Dec<sup>−1</sup>, which is comparable to most of the present MoS<inf>2</inf>/Graphene HER catalysts. The (0D/3D) MoS<inf>2</inf>/P-rGO exhibits as an efficient noble metal free HER catalyst, and has great potential for the electrochemical hydrogen production.
