Unique Reversible Conversion-Type Mechanism Enhanced Cathode Performance in Amorphous Molybdenum Polysulfide.

A unique reversible conversion-type mechanism is reported in the amorphous molybdenum polysulfide (a-MoS) cathode material. The lithiation products of metallic Mo and LiS rather than Mo and LiS species have been detected. This process could yield a high discharge capacity of 746 mAh g.

Electrodeposited MoS Films from (NH)MoS·2HO for Electrocatalysis of Hydrogen Evolution Reaction.

Molybdenum sulfides are considered to be one kind of the promising candidates as cheap and efficient electrocatalysts for hydrogen evolution reaction (HER). But this is still a gap on electrocatalytic performance toward Pt. To further enhance electrocatalytic activity of molybdenum sulfides, in this work, we prepared MoS films with high ratio of sulfur to molybdenum by electrodeposition.
