摘要
研究提供以脱铁蛋白(apo-ferritin)为材料,采用生物模板技术制备出的一种新型纳米碳质材料——碳纳米球及其制备方法。与国际上的研究热点碳纳米管相比,空心碳纳米球结构特殊,比重小(1.3 g/cm3)、比表面积(>600 m2/g)大,丰富的纳米尺度空隙。空心碳纳米球在储氢、锂离子负极材料等领域应具有类似于碳纳米管的潜在的巨大应用前景。
Using apo- ferritin as raw material, a new carbon nano- sized material, hollow carbon nano- sphere, has been prepared with biological template method in this paper. Compared to carbon nanotube, hollow carbon nano- sphere has special microstructure, small proportion (1.3 mg/m^3), larger specific surface area (〉 600 m^2/g) and abundant nano - sized void. Therefore, it has remarkably potential application in hydrogen storage material and anode material for lithium secondary batteries.
