Construction of TiO/TiOF heterojunction as a cathode material for high-performance Mg/Li hybrid-ion batteries.

Anatase TiO has attracted significant interest as a cathode material for Mg-ion batteries or Mg/Li hybrid-ion batteries. However, owing to the semiconductor property and slower Mg diffusion kinetics it still suffers from poor electrochemical performance. Herein, a TiO/TiOF heterojunction consisting of in situ formed TiO sheets and TiOF rods, was prepared by adjusting the amount of HF in the hydrothermal process, and used as cathode of Mg/Li hybrid-ion battery.

Supra Hydrolytic Catalysis of Ni Fe/rGO for Hydrogen Generation.

Light metal hydrolysis for hydrogen supply is well suited for portable hydrogen fuel cells. The addition of catalysts can substantially aid Mg hydrolysis. However, there is a lack of clear catalytic mechanism to guide the design of efficient catalysts.
