Hierarchical porous carbon microspheres derived from porous starch for use in…

Abstract. Porous starch was used as a precursor for hierarchical porous carbon microspheres. The preparation consisted of stabilisation, carbonisation and KOH activation, and the resultant hierarchical porous carbon microspheres had a large BET surface area of 3251 m2 g-1. Due to the large surface area and the hierarchical pore structure, electrodes made of the hierarchical porous carbon m…
