Porous
carbon
has
continuously
been
explored
based
on
biomass
for
green
energy
storage
due
to
its
abundant,
renewable,
environmentally
friendly
resource,
economical
features,
and
thermal-chemical
stability.
Therefore,
this
study
aimed
present
porous
derived
from
sugarcane
or
Saccharum
officinarum
L.
leaf
as
a
precursor,
achieved
through
KOH
activation
strategy
that
combines
two-step
pyrolysis
process.
The
synthesized
material
exhibited
an
interconnected
3D
hierarchical
structure,
high
specific
surface
area
of
752
m2/g,
purity
91.38%.
Supercapacitor
cell
electrode
had
the
highest
capacitance
471
F/g
induced
by
0.5
M
KOH.
Furthermore,
in
1
H2SO4
electrolyte
solution,
symmetrical
supercapacitor
electrodes
produced
65.55
Wh/Kg
at
power
output
329
W/Kg.
As
result,
sustainable
method
was
established
using
source
is
applied
high-performance
material.
