Reflux with ethylene glycol as medium was employed to produce the nanocomposite. Crystal structure characterization using X-Ray diffraction shows the nanocomposites have good crystalinity without any impurity. Scanning electron microscopy and transmission electron microscopy characterization results show SnO2 has spherical shape and well distributed on the graphene layer. The size of SnO2 particles is around 5-8 nm. To confirm the improvement effect of grapheme addition to SnO2, sensor testing was conducted toward 30 ppm carbon monoxide (CO) gas at 150 °C compared with pure SnO2 and pure graphene. The sensor responses are 88.11%, 52.84%, and 0.93%, respectively.[/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]Carbon monoxide sensor,Graphene layers,Graphene nanocomposites,Polyol methods,Sensing performance,Sensor response,Spherical shape,Structure characterization[/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 monoxide,Polyol method,sensing performance,SnO-graphene nanocomposite[/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]Manuscript received June 18, 2017; revised July 31, 2017 and September 19, 2017; accepted October 10, 2017.
