Potassium electrochemical optimization of the MoS<sub>2</sub> catalytic hydrogen evolution reaction performance
This study presents a flexible self-supporting C@MoS<sub><i>x</i></sub>@pCNF electrode, prepared <i>via</i> potassium electrochemical intercalation, which fragments MoS<sub>2</sub> into smaller, amorphous nanoparticles. The amorphous MoS<sub><i>x</i></sub> shows enhanced active sites and superior hydrophilic/aerophobic properties. The electrode demonstrates excellent HER performance with a low overpotential of 51 mV at 10 mA cm<sup>-2</sup> and a Tafel slope of 77 mV dec<sup>-1</sup>, offering a new strategy for improving MoS<sub>2</sub> catalysis.
