3D flower-like molybdenum disulfide modified graphite felt as a positive material for vanadium redox flow batteries.

3D flower-like molybdenum disulfide microsphere modified graphite felt (MoS/GF) with excellent electrocatalytic activity and redox reversibility for the VO/VO couple is successfully fabricated by a facile hydrothermal method. The results show that the hydrothermal reaction time has a deep influence on the MoS structure; an open 3D flower-like MoS structure with a layer spacing of 0.63 nm is uniformly grafted on the GF surface for a reaction time of 36 h.
