A poly(amino acid)-based approach for scalable synthesis of micro-/mesoporous carbon (PC) with high specific surface area and narrow distribution of micro- and mesopores is presented. Using cross-linked poly aspartic acid as a precursor, PC was obtained by in situ one-step carbonization without the activating agent. The resulting PC had an ultrahigh adsorption capacity for H2 (4.43 wt %) and CH4 (4.49 mmol g–1). This novel method could significantly decrease the wastewater hazards caused by washout of the considerable amount of the activating agent. The PC showed promising application in gas adsorption and storage.

聚天冬氨酸衍生的微孔/中孔碳,用于超高的H2和CH4吸附。

提出了一种基于聚氨基酸的可扩展合成具有高比表面积,微孔和中孔分布较窄的微/中碳(PC)的方法。使用交联的聚天冬氨酸作为前体,通过不加活化剂的原位一步碳化获得PC。所得的PC对H 2(4.43 wt%)和CH 4(4.49 mmol g –1)具有极高的吸附能力。这种新方法可以显着减少因冲洗掉大量活化剂而造成的废水危害。PC在气体吸附和存储方面显示出广阔的应用前景。
