Pd/TiO2(n)/Ti sensors showed relatively poor H2 sensing properties in air, in comparison with Pd/anodic-TiO2(n)/Ti sensors constructed with an anodized TiO2 film equipped with a top Pd film electrode and a bottom Ti plate electrode, which were reported in our previous studies. On the other hand, Pd/Nb2O5(n)/Nb sensors showed relatively larger H2 response with fast response and recovery speeds than Pd/TiO2(n)/Ti sensors in air under high forward bias conditions. A Pd/Nb2O5(450)/Ti sensor, which was fabricated by radio-frequency magnetron sputtering of Nb metal on a Ti substrate followed by thermal oxidation at 450 °C, showed the largest H2 response and relatively fast response and recovery speeds in air, among the sensors tested. In addition, H2 response of the Pd/Nb2O5(450)/Ti sensor in air was much lower than that in N2, but the logarithm of H2 response was almost proportional to the logarithm of H2 concentration in a wide range of H2 concentration (10-8000 ppm) in air, and the H2 sensitivity in air was much higher than that in N2.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Sensors and Actuators B: Chemical, 142(1), pp.97-104; 2009","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier BV"}]},"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.2009.07.058","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2009 Elsevier B.V.
