“Ultrahigh surface area carbons (USACs, e.g., >2000 m2/g) are attracting tremendous attention due to their outstanding performance in energy-related applications.”
Observations such as this have lead to the search for an easy and cheap method of producing these materials – which find uses like supercapacitor electrodes, catalyst supports, and gas sorbents etc etc. A research team from Oak Ridge National Laboratory, and the University of Tennessee, (Pengfei Zhang, Zhiyong Zhang, Jihua Chen and Sheng Dai) have, between them, developed just such a method. Their study, describing the process in detail, is published in the specialist journal Carbon, Volume 93, November 2015, Pages 39–47, and is entitled ‘Ultrahigh surface area carbon from carbonated beverages: Combining self-templating process and in situ activation’
“This promising process provides an exceptional route to highly porous carbon materials.”
– say the team, noting that Coca Cola®, Pepsi Cola®, Dr. Pepper®, and Fanta® all perform rather well.
