In addition, H2-sensing properties of these sensors have also been investigated in the same gaseous conditions, to evaluate their CO selectivity against H2. All of the EC(MO) sensors showed relatively small changes in electromotive force (EMF), i.e. responses, to both CO and H2, but the Au loading to In2O3 and ZnO drastically improved the magnitude of CO response of the EC(In2O3) and EC(ZnO) sensors, respectively. The EC(2.0Au/In2O3(400air)) sensor showed larger CO response, faster CO response speed, excellent CO selectivity against H2 and better long-term stability than those of the EC(2.0Au/ZnO(400air)) sensor. The influence of moisture on the CO response of the EC(2.0Au/In2O3(400air)) sensor was almost negligible in the humidity range of 40?100%RH. The magnitude of CO response of the EC(2.0Au/In2O3(400air)) sensor in wet synthetic air showed a good linear relationship with CO concentration, but the CO response was largely affected by the concentration of O2. These results indicate that the EMF of the EC(2.0Au/In2O3(400air)) sensor is probably determined by the mixed potential resulting from CO oxidation and O2 reduction. The heat-treatment conditions of the 2.0 wt% Au-loaded In2O3 powder largely affected the CO-sensing properties of the EC(2.0Au/In2O3(Tm)) sensors. Among these sensors heat-treated in various conditions, the as-fabricated EC(2.0Au/In2O3(250H2)) sensor showed the most excellent CO selectivity against H2 in their concentration range of 10?3000 ppm.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Electrochimica Acta, 166, pp.232-243; 2015","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd"}]},"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.electacta.2015.03.045","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2015, Elsevier Ltd.
