摘要: Abstract TiO2/carbon hollow spheres (TiO2/C-HSs) have been successfully prepared using a template method. During the synthesis procedures, SiO2 were used as template, titanium tert-butoxide and dopamine TiO2 carbon precursor, respectively. The TiO2/C-HSs characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption measurements, scanning electron microscopy (SEM), transmission (TEM), thermogravimetry (TGA) raman spectra analysis. When utilized anode materials for sodium-ion batteries, can deliver high specific capacity remarkable rate performance. excellent electrochemical performance of be ascribed to sphere structure, existence large surface area porous structure.
