Effect of catalytic graphitization on the electrochemical behavior of wood derived carbons for use in supercapacitors

Porous graphitic carbons were successfully obtained from wood precursors through pyrolysis using a transition metal as catalyst. Once the catalyst is removed, the resulting material mimics the microstructure of the wood and presents high surface area, open and interconnected porosity and large pore...
