中文摘要：

精力危机和环境污染是那个人文学科将面对为的严肃的挑战长期。尽管有巨大的努力，环境地友好的方法的发展仍然正在质问制作新精力材料。第一次，这里，我们报导新策略制作各种各样的做的碳 nanofiber (CNF ) 由细菌的纤维素(BC ) 的热分解的 aerogels 与不同有毒的器官的染料吸附了或被染的薄皮。建议策略使把有毒的染料从废水移开然后综合可能把染的 BC 薄皮用作先锋的做的 CNF aerogels。与为准备的另外的报导过程相比， heteroatom 做了碳(HDC ) nanomaterials，现在的合成方法有一些重要优点例如是绿的，一般、便宜、容易可伸缩。而且，象为氧减小反应(ORR ) 的 electrocatalysts 并且作为为 supercapacitors 的电极材料潜在的同样准备的做的 CNF aerogels 展览伟人。

英文摘要：

The energy crisis and environmental pollution are serious challenges that humanity will face for the long-term. Despite tremendous efforts, the development of environmentally friendly methods to fabricate new energy materials is still challenging. Here we report, for the first time, a new strategy to fabricate various doped carbon nanofiber （CNF） aerogels by pyrolysis of bacterial cellulose （BC） pellicles which had adsorbed or were dyed with different toxic organic dyes. The proposed strategy makes it possible to remove the toxic dyes from waste-water and then synthesize doped CNF aerogels using the dyed BC pellicles as precursors. Compared with other reported processes for preparing heteroatom doped carbon （HDC） nanomaterials, the present synthetic method has some significant advantages, such as being green, general, low-cost and easily scalable. Moreover, the as-prepared doped CNF aerogels exhibit great potential as electrocatalysts for the oxygen reduction reaction （ORR） and as electrode materials for supercapacitors.
