Abstract
Multilayered SnO2hollow microspheres (MHS-SnO2) have been successfully synthesized via a solvothermal method by using glycol-water as solvent. The morphology, composition and structure of the product have been characterized by field-emission scanning electron microscopy (FESEM) with an energy dispersive X-ray (EDX) spectroscopy, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) with selected area electron diffraction (SAED) and X-ray diffraction (XRD). The FESEM, TEM and HRTEM images indicate that the as-prepared microspheres show multilayered structure and the wall of the hollow microspheres is composed of single crystalline nanoparticles. Study on hydrogen absorption characteristics of MHS-SnO2performed at 373 K shows a good absorption capacity of 0.85 wt.%.
