Direct and mild non-hydroxide activation of biomass to carbons with enhanced CO<sub>2</sub> storage capacity
Afnan Altwala, Robert Mokaya
Abstract
Direct activation of biomass, via a simple and lower cost one-step process, with potassium oxalate as a mild and less corrosive agent, yields activated carbon with properties and CO 2 uptake comparable or superior to conventionally prepared activated carbons.
