The precursor solution was formed into droplets by a nebulization process under nitrogen gas flow through inside the furnace tube. Simultaneously, the oil was decomposed as nano carbons by heating mechanism onto the surface of activated carbons used as substrate. By varying the catalyst concentration dissolved in the oil (0.015, 0.02 and 0.025 g/ml) and operating temperature (650, 700 and 750 °C), the structure or morphology of the as-prepared nano carbons can be controlled. The structure and morphology of the carbon samples were observed using scanning electron microscopy (SEM). Their graphite and crystal structure was characterized by Raman spectroscopy and X-ray diffraction (XRD). The experimental results showed that carbon nanotubes (CNTs) were formed at a high catalyst concentration (0.025 g/ml), whereas carbon spheres (CNSs) were found at a lower concentration (0.015 and 0.02 g/ml) for the synthesis process conducted at 650 °C. Similarly, agglomerated CNSs were also obtained for the deposition conducted at high operating temperature of 700 and 750 °C and catalyst concentration of 0.025 g/ml.[/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]Catalyst concentration,CNSs,CNTs,High operating temperature,Nebulized spray pyrolysis,Operating temperature,Structure and morphology,Waste cooking oil[/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]CNSs,CNTs,Spray pyrolysis,Waste cooking oil[/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]https://doi.org/10.1166/jnn.2017.14177[/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]
