It is one of the unique materials, showing excellent and unique physical and chemical properties, including high electrical and thermal conductivities, high surface area, high mechanical strength, and chemically inert. Its interesting properties did not only improve the capabilities of the existing equipment but also it could be developed to be a variety of novel equipment. The commercial carbon nanostructure in this research was prepared by a technology process which is relatively much simpler than the process of the existing commercial carbon nanostructures in the market. In this study, catalytic graphitization processing was performed by using cellulose from Oryza sativa pulp as a precursor and iron (III) chloride hexahydrate as a catalyst. Chemical and mechanical treatments were carried out to separate the cellulose from Oryza sativa pulp. Catalyst impregnation into cellulose was carried out by heating a mixture of cellulose and the catalyst in an oven up to 48 hours. Graphitization process was then performed at temperatures of 600-800°C in an inert atmosphere of N2 for two hours. Based on XRD analysis results, the peak at diffraction angel 2θ of 26° was observed, corresponding to the (002) crystal plane orientation of the graphite structure. The characterization results of FT-IR Spectrophotometer showed the aromatic functional group, indicating the presence of C = C bond at the wave numbers of 1500-1650 cm-1 which is the basis of the graphite structure; while the peak appearance at the wavenumbers of 480-510 cm-1 was corresponded to the characteristics for the Fe-O interaction. SEM results showed that the carbon nanostructures were 30-80 nm in diameter and had the length of up to 2μm. However, TEM results showed the formation of carbon nanocoil-based graphite with the formation of transition carbide compounds to produce graphite.[/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]Aromatic functional groups,Carbon Nanostructures,Catalytic graphitization,Graphitization process,High mechanical strength,Oryza sativa,Physical and chemical properties,Synthesis and characterizations[/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]Carbon nanostructure,Catalytic graphitization,Cellulose,Graphite,Oryza sativa pulp[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
