Abstract
Molybdenum disulfide (MoS2) has become a promising electrochemical catalyst for reduction of protons to hydrogen in the so-called hydrogen evolution reaction (HER). In order to increase the \HER\ activity, a huge effort has been made to design MoS2 catalysts with affording more active sites and higher conductivity. In this paper, an efficient \HER\ electrochemical catalyst has been developed through an in-situ reduction of ammonium tetrathiomolybdate (ATTM) on carbon fibers (CFs) to afford layer-expanded MoS2/CFs composites (LE-MoS2/CFs). X-ray diffraction (XRD) indicates the interlayer of MoS2 nanosheets was expanded with d spacing 9.9
