Cubic spinel In_4SnS_8: Electrical transport properties and electrochemical hydrogen storage properties

摘要

In this work, electrical transport properties and electrochemical hydrogen storage properties of a cubic spinel In_4SnS_8 hierarchical nanostructure were investigated. A simple single layer device exhibits non-linear current-voltage (I-V) characteristics. The detailed electrical transport properties of the sample indicated that the conduction mechanism varied in different external voltage regions. Derived from the typical spinel system of the A[B_2]X_4 (A: Zn, Cu, Sn, B: In, Ga, X: S, Se) ternary chalcogenides, this thiospinel compound also shows high electrochemical hydrogen storage of 127 mAh g~(-1) and its mechanism is discussed.
