T
he increase in climate related natural adversities have
reinforced the obvious need of diminishing green-house
gaseous emissions, predominantly those of CO
2
and is leading
government agencies around the world to develop a sequence
of roadmaps, which aspire at moving forward to a low carbon
economy. Carbon capture and storage (CCS) has been identified
as one of the key technologies that could contribute in a greater
degree to reach the CO
2
emission reduction targets. In the present
study we have established a synthesis route for production
of porous graphene material from the oil palm empty fruit
bunches (EFB) for CO
2
capture. We have used a wide range of
instrumental techniques including scanning electron microscopy,
atomic force microscopy, transmission electron microscopy,
X-ray photoelectron spectroscopy, X-ray diffraction and Raman
spectroscopy together with the Brunauer–Emmett–Teller surface
area analysis and density functional theory models to provide
insights into morphological and structural characteristics of
the porous graphene. The porous graphene show excellent
performance as adsorbents for post combustion CO
2
capture
(>2.0 mmol g−1) which is considerably higher than other
competitive CO
2
adsorbents, including zeolite, activated carbon
and some metal organic frameworks. Thus, these results suggest
that the biomass waste used in current study could be effectively
valorized as efficient CO
2
adsorbent under post combustion
conditions.
