ABSTRACT
Porous activated carbon monolith derived from renewable and environmentally
friendly biomass of‘red shoots’ leaves (Syzygium oleana)was prepared for
electrode material of supercapacitors. The raw materials were converted into
biochar by using ZnCl2 impregnated and one-stage integrated pyrolysis. The
samples were chemically activated using the 1 M ZnCl2, which was then
converted into monolith/pellet by using a hydraulic press. The carbon monolith
were then one-stage integrated pyrolysisboth carbonization and physical
activation. This study is focused in different carbonization temperatureincluding
500 °C, 600 °C and 700 °C. The reduction of density in the activated carbon
monoliths have been reviewed as physical properties. In addition, the XRD and
FTIR characterization also reviewed. Based on this, the activated carbon monolith
from‘red shoots’ leaves biomass for supercapacitors deliver a high specific
capacitance of 138.5 F g-1 in 1 M H2SO4 aqueous electrolyte at low scanning rate
of 1 mVs-1. Furthermore, a remarkable energy density of 69.25 Wh kg-1 at a
power density of 249.549 W kg-1 has been achieved. This results demonstrate the
successfully conversion ‘red shoots’ leaves (Syzygiumoleana) biomass into
renewable and environmentally friendly electrode supercapacitor energy storage.
Keywords: Red shoots leaves, Carbonization, Activated carbon, Electrode
