Three-dimensional graphene architectures were synthesized from a new source, chicken feather, a bio-waste. Here ferric chloride (FeCl₃) was used as a self-originator template, with a high C/O ratio (21:1). The introduction of Fe^3＋ ion into the activated frame of carbon generated graphene nanostructure. X-ray photoelectron spectroscopy was used to analyse the defects in the prepared graphene. The obtained structures were found to be unique nanoplatelets and three-dimensional pyramid-like structure. Its DC conductivity has been tested within the temperature range of 20 to 300K and their temperature-dependent conduction mechanism was established. At $\sim$100 K and $\sim$50 K, a 3D–2D and Mott–ES type cross-over were observed respectively, with varied hopping length. The conductivity was found to be decreased with lowering temperature which was similarly observed in metals.

三维石墨烯架构是从一种新的来源鸡羽毛，一种生物废物中合成的。此处，氯化铁（FeCl ₃）被用作具有高C / O比（21：1）的自发模板。将Fe ³⁺离子引入碳生成的石墨烯纳米结构的活化框架中。用X射线光电子能谱分析所制备的石墨烯中的缺陷。发现获得的结构是独特的纳米片和三维金字塔状结构。它的直流电导率已在20至300K的温度范围内进行了测试，并建立了与温度有关的传导机理。在$〜$100 K和 $〜$分别观察到50 K，3D–2D和Mott–ES型交叉，其跳跃长度不同。发现电导率随温度降低而降低，这在金属中类似地观察到。
