Abstract

Sucrose-derived layered carbon materials hold promise for energy storage applications, but their synthesis is challenging due to sucrose's molecular structure and pyrolysis behavior. This work demonstrates the successful synthesis of layered carbon from sucrose using FeCl₃ as a catalyst. The resulting layered carbon was then functionalized via Hummer's oxidation and Fenton reaction methods to enhance proton conductivity. Characterization by SEM, FTIR, and XPS confirmed the layered structure and the presence of oxygenated functional groups after oxidation. Electrochemical measurements revealed significantly improved proton conductivity, with the Fenton-modified layered carbon exhibiting the highest conductivity of 3.27 × 10- 3 S cm-¹ in the in-plane direction at 90% relative humidity and 55 °C. These results suggest the potential of this sucrose-derived, functionalized layered carbon material for use in advanced energy storage technologies.

具有优异质子导电性能的蔗糖衍生功能化层碳。
蔗糖衍生的层状碳材料有望用于储能应用,但由于蔗糖的分子结构和热解行为,它们的合成具有挑战性。这项工作证明了用FeCl₃作为催化剂成功地从蔗糖合成了层状碳。然后通过Hummer的氧化和Fenton反应方法对所得层状碳进行功能化,以提高质子的导电性。通过SEM, FTIR和XPS表征,证实了氧化后的层状结构和含氧官能团的存在。电化学测量结果表明,在90%相对湿度和55℃条件下,fenton修饰的层状碳在平面方向上的电导率最高,为3.27 × 10- 3 S cm-¹。这些结果表明,这种蔗糖衍生的功能化层状碳材料具有用于先进储能技术的潜力。

期刊介绍: Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
