[资源] 最新ACS上发表的水热合成法制备Au掺杂的Li4Ti5O12

水热合成法制备纳米尺度的LTO具有多重优势，颗粒形貌、电池高倍率性能都能很好的表明此方法的优异性。
A facile, green strategy is explored to synthesize mesoporous Au/Li4Ti5O12 spheres
based on in situ conversion of titanium glycolate in LiOH aqueous solution. Compared with TiO2 precursors, titanium glycolate possesses some strengths: (i) fast and easy preparation; (ii) direct reaction with LiOH without introduce of TiO2 impurity. In the synthesis, the produced chemical waste is only the mixed solvent of acetone and ethylene glycol (EG). Furthermore, acetone and EG in chemical waste can be easily separated by distillation and reused in the next synthesis process due to the great difference between their boiling points. In particular, the as-prepared mesoporous Au/Li4Ti5O12 spheres combines the advantages of large specific surface area (166 m2/g) and good electronic conduction enhanced by Au nanoparticles when used as an anode electrode material. The electrochemical tests show that the mesoporous Au/Li4Ti5O12 spheres display excellent high rate
capability and cycling performance.
