AI Article Synopsis
- Amorphous molybdenum sulfide (MoS) is chemically bonded to reduced graphene oxide (r-GO) through a straightforward one-pot reaction that reduces GO and adds heteroatoms.
- Oxygen atoms act as a bridge between MoS and GO, enhancing the dispersion of MoS particles, controlling their growth, and increasing the number of active sulfur sites.
- This combination results in an efficient electrocatalyst for hydrogen evolution, showing a low overpotential of -157 mV and remaining stable at 95% activity after 1000 cycles.
Article Abstract
Amorphous molybdenum sulfide (MoS) 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 MoS and GO and play a crucial role in the fine dispersion of the MoS particles, control of planar MoS growth, 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.
