title: Bi-axial grown amorphous MoSxbridged with oxygen on r-GO as a superior stable and efficient nonprecious catalyst for hydrogen evolution.
abstract: Amorphous molybdenum sulfide (MoSx) is covalently anchored to reduced graphene oxide (r-GO) via a simple one-pot reaction, thereby inducing the reduction of GO and simultaneous doping of heteroatoms on the GO. The oxygen atoms form a bridged between MoSxand GO and play a crucial role in the fine dispersion of the MoSxparticles, control of planar MoSxgrowth, and increase of exposed active sulfur sites. This bridging leads to highly efficient (-157 mV overpotential and 41 mV/decade Tafel slope) and stable (95% versus initial activity after 1000 cycles) electrocatalyst for hydrogen evolution.
