Production of graphene in large scale and low cost are attracting topic in recent years. Previous study shows that production of graphene from biomass via pyrolysis has low yield of graphene. In this study, we produced graphene sheets from oil palm empty fruit bunch via two-stages pyrolysis to increase the yield. The produced graphene sheets were characterized by scanning electron microscopy, transmission electron microscopy, Raman scattering, and X-ray diffraction. Surface properties (i.e. effective surface areas, pore volumes, and pore size distributions) were studied by nitrogen adsorption-desorption measurements. Effect of the first stage temperature of pyrolysis on the yield, structure, and properties of graphene has been investigated. Our result indicated that two-stages pyrolysis could increase the yield of graphene up to 70%. Graphene sheets shows favorable features of nanosheet frameworks (4-10 atomic layers) and high surface area (870 m2 g-1).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Atomic layer,Carbon atoms,Effective surface area,Graphene sheets,High surface area,Nitrogen adsorption desorption,Oil palm empty fruit bunch,Scanning electrons[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is supported by Badan Pengelola Dana Perkebunan Kelapa Sawit, funding year of 2018.
