Porous carbons from sustainable sources and mild activation for targeted high-performance CO2 capture and storage (2020)
Journal Article
Aljumialy, A. M., & Mokaya, R. (2020). Porous carbons from sustainable sources and mild activation for targeted high-performance CO2 capture and storage. Materials Advances, 1(9), 3267-3280. https://doi.org/10.1039/d0ma00449a

Carbon activation typically involves corrosive activating reagents such as KOH and NaOH. In this report, a less corrosive activating agent, i.e., potassium oxalate (PO), was explored for the preparation of activated carbons from biomass (hydrochar fr...
