Facile synthesis of stable structured MoS^sub 2^-Mo-CNFs heteroarchitecture with enhanced hydrogen evolution

3D structured MoS2 are grown in-situ on Mo particles embedded carbon nanofibers (CNFs) via a hydrothermal method. Due to this special structure, the bonding and effective electron delivery between CNFs and MoS2 are both enhanced, and which will exhibits a better hydrogen evolution activity. The onse...

Zusammenfassung:3D structured MoS2 are grown in-situ on Mo particles embedded carbon nanofibers (CNFs) via a hydrothermal method. Due to this special structure, the bonding and effective electron delivery between CNFs and MoS2 are both enhanced, and which will exhibits a better hydrogen evolution activity. The onset potential of this MoS2-Mo-CNFs catalyst will decreased to 60 mV compared to the 90 mV for the MoS2-CNFs. And its current density nearly no change with 5000 cycles which is better than the 32.3% decrease of MoS2-CNFs at η = 300 mV (V vs RHE).
