Green and scalable synthesis of 3D porous carbons microstructures as electrode materials for high rate capability supercapacitors.

Porous carbon nanostructures have long been studied because of their importance in many natural phenomena and their use in numerous applications. A more recent development is the ability to produce porous carbon materials with tuneable properties for electrochemical applications, which has enabled new research directions towards the production of suitable carbon materials for energy storage applications. Thus, this work explores the activation of carbon from polyaniline (PANI) using a less-corrosive potassium carbonate (KCO) salt, with different mass ratios of PANI and the activating agent (KCO as compared to commonly used KOH).
