ZnO-Gr nanocomposite was varied with ratio of 1:1, 1:3, and 1:5 to obtain the optimum composition in responding to CO gas. The sensing layer was exposed by CO gas to 5 concentration variations at room temperature and 1 concentration at 2 high temperature. Morphological structure of ZnO-Gr was presented through Scanning Electron Microscopy (SEM). It was found that ZnO-Gr nanocomposite with ratio of 1:3 at room temperature generated the highest % response to CO gas sensing. Decreased resistance occurs in step of increasing temperature. The property of semiconductor changes from p to n-type above 100°C temperature to CO gas exposure.[/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]Alumina substrates,Concentration variation,Graphene nanocomposites,Hydrothermal methods,Increasing temperatures,Morphological structures,Optimum composition,Zinc oxide (ZnO)[/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]Gas Sensor,Graphene,Hydrothermal Method,Nanocomposite ZnO-Gr,Scanning Electron Microscopy,Zinc Oxide[/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/10.1109/ISESD.2019.8909412[/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]
