Abstract

In this work, electrical transport properties and electrochemical hydrogen storage properties of a cubic spinel In₄SnS₈ 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[B₂]X₄ (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.
