The specific surface area and pore volume of the m-SnO2 powder prepared from Na2SnO3・3H2O as a tin source and n-cetylpyridinium chloride monohydrate (C16PyCl; (C5H5NC16H33)Cl・H2O) as a template under a fixed pH value of 10 (m-SnO2(1)) were larger than those of the m-SnO2 powders prepared from SnCl4・5H2O as a tin source and aerosol-OT (AOT; C20H37O7SNa) as a template under different pH conditions (m-SnO2(2)-n; n is the value of pH of the precursor solution). However, the specific surface area of m-SnO2(1) decreased drastically by post-grinding, while m-SnO2(2)-n powders with small secondary agglomerates showed only a slight decrease in specific surface area during post-grinding. In addition, m-SnO2(2)-n sensors exhibited better H2 response and lower resistance than those of m-SnO2(1) sensor, especially at low operating temperatures, probably because of moderately developed mesopores which promoted easier diffusion of H2 to the most sensitive region of the surface of SnO2 particles.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Sensors and Actuators, B: Chemical, 141(2), pp.465-470; 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.2009.07.035","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2009 Elsevier B.V.
