英文摘要: Porous SnO2 nanoflakes with loose-packed structure were synthesized by calcination of SnS2 precursors that were obtained through solvothermal method at low temperature. The as-obtained SnO2 product had a three-dimensional porous structure with relatively high specific surface area. It was found that the SnO2 nanoflakes inherited the morphology of precursor while numerous pores were formed after the annealing process. The combined techniques of X-ray diffraction, energy-dispersive spectrum, field emission scanning electron microscopy, and (high-resolution) transmission electron microscopy were used for characterization of the as-prepared SnO2 product. Moreover, the porous SnO2 nanoflakes with loose-packed structure could be used as gas sensors for detecting ethanol and acted as anode for lithium ion batteries. Our study shows that the as-prepared SnO2 nanoflakes not only exhibit good response and reversibility to ethanol gas but also display enhanced Li-ion storage capability.
