Original Paper: Sol–gel and hybrid materials for catalytic, photoelectrochemical, and sensor applications


This work reported the preparation of amorphous MoSx aerogel and MoSx/carbon nanotubes composite aerogels by a modified epoxide addition sol–gel method. In this process, propylene epoxide scavenged the protons from a S–H-contained organic acid (dl-Mercaptosuccinic acid) and promoted the interactions between (NH4)6Mo7O24•4H2O and the functional groups in the organic acid to form a gel. The sulfur and molybdenum contained a wet gel turned into an amorphous MoSx aerogel after supercritical drying in ethanol. Carbon nanotubes can be further incorporated into the aerogel backbone, which can extend the specific surface area and alter the pore structures in the composite aerogels. Such composite aerogels showed good catalytic performance in electrochemical hydrogen evolution reactions.

MoSx aerogels can be prepared by the modified epoxide-adding method and showed good catalytic activity toward HER.


  • Epoxide addition method has been adopted to synthesize amorphous molybdenum sulfide aerogel.

  • High surface area (up to 265.5 m2/g) and the developed pore structure (pore volume up to 0.89 cm3/g) have been achieved.

  • Low overpotential and high activity toward hydrogen evolution have been observed.
