The n(Au/Pd)/mp-Al2O3 sensors showed larger responses to these target gases at lower temperatures than those of sensors fabricated with mp-Al2O3 powders loaded with Au and Pd by general impregnation technique (n(Au-Pd)/mp-Al2O3 sensors, Au:Pd = 1:4 in weight), especially when the amount of Au and Pd loaded onto the mp-Al2O3 powders was reduced (?0.5 wt%). These sensing properties seem to be largely dependent on the morphological and compositional characteristics of Au and Pd loaded on the γ-alumina surface. In addition, the n(Au/Pd)/mp-Al2O3 sensors showed much larger response to ethanol than those to toluene and n-hexane, probably because of the difference in the magnitude of polarity (dipole moment and dielectric constant) of their molecules. However, the sensors obviously detected even 10 ppm n-hexane with the extremely low dipole moment and dielectric constant. These results promise that the n(Au/Pd)/mp-Al2O3 sensors can detect the lower concentration of these gases as well as other VOCs.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Sensors and Actuators B: Chemical, 202, pp.748-757; 2014","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.snb.2014.06.016","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2014 Elsevier B.V.
