Facile precipitation synthesis and characterization of Zn2SnO4 nanostructures and their application as hydrogen storage materials

A facile precipitation method with the subsequent thermal treatment has been developed for the synthesis of Zn2SnO4 nanostructures in presence of tetraethylenepentamine (TEPA) with long chain as a cappingand basic agent. The effect of different experimental parameters were studied to reach optimum size and morphology conditions. In this paper, hydrogen storage capacity of Zn2SnO4 nanoparticle reported for thefirst time. Furthermore, the mesoporous of Zn2SnO4 nanoparticle showed high electrochemical hydrogen storage capacities at room temperature. After 10 cycles, the discharging capacities of the electrode is 810 mAh/g. These results indicates that the mesoporous Zn2SnO4 nanoparticle may be potentially applied for electrochemical hydrogen storage
