Hydrogen is considered as an energy storage and carrier for future energy demand. The ideal resource of hydrogen is water, as it is abundant and contains no carbon. Sustainable hydrogen can be produced from water splitting using electricity from renewable energy sources. Water splitting requires the HER, which needs the catalytic activity. While platinum and other precious metals are the best catalyst for the HER, replacing rare and expensive catalysts with earth-abundant materials would represent a significant step toward making hydrogen as an alternative energy source and facilitate the transition to a hydrogen economy. Hence, new efficient materials for renewable hydrogen production are greatly needed.

In this presentation, we will present that cost-effective way to synthesize hierarchically nanostructured MoS₂ nanofibers and demonstrate them ability to produce hydrogen by water splitting. We fabricated and optimized a perpendicularly grown nanosheets on nanofiber core with high exposure of catalytic active edge sites and good electrical contact with core nanofibers using electrospinning process, which can produce the nanomaterials on industrial scale.
