Synthesis, characterization and hydrogen storage capacity of MS2 (M = Mo, Ti) nanotubes

The structure, morphology and hydrogen-storage capacity of MS2 (M = Mo, Ti) nanotubes prepared by different experimental methods were studied. It was found that the MoS2 nanotubes treated by KOH displayed the gaseous storage capacity of 1.2 wt% hydrogen (under the hydrogen pressure of 3 MPa and 25°C) and the electrochemical discharge capacity of 262 mAh/g (at the discharge current density of 50 mA/g and 25°C) that corresponds to about 1.0 wt % hydrogen. In comparison, TiS2 nanotubes can store 2.5 wt% hydrogen under the hydrogen pressure of 4 MPa and 25°C. The results show that MS2 compound nanotubes are promising materials for hydrogen storage.

Organic conjugated carbonyl compounds as electrode materials for lithium-ion batteries

Organic conjugated carbonyl compounds provide potential advantages such as high specific capacity, low-cost, and environmental benignancy. These merits make them promising candidates as electrode materials for next-generation green Lithiumion batteries (LIBs). The research progresses on organic conjugated carbonyl compound electrode materials with particular focus on the mechanism of electrochemical reaction of conjugated carbonyl compound electrode materials, small molecular conjugated carbonyl compounds and conjugated carbonyl polymers are reviewed. The new strategies to improve the performance of the electrode materials are pointed out, and the future development direction is given.
