Abstract

The increase in climate related natural adversities have reinforced the obvious need of diminishing green-house gaseous emissions, predominantly those of CO2 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 CO2 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 CO2 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 CO2 capture (>2.0 mmol g−1) which is considerably higher than other competitive CO2 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 CO2 adsorbent under post combustion conditions
