The mesoporous structure was controlled by C20H37O 7SNa, while the macroporous structure was controlled by polymethylmethacrylate (PMMA) microspheres. The introduction of macropores by the addition of PMMA microspheres into mp-SnO2 tends to increase the pore diameter and crystallite size. The large amount of macropores introduced into mp-SnO2 sensors by the addition of PMMA microspheres in the preparation process significantly increased the resistance of all the sensors. Among all those tested, the mp-SnO2 sensor with only 5 wt% Sb 2O5 added exhibited the largest response at 400°C. The 70% response and recovery times could be reduced by the introduction of macropores.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Sensors and Materials, 21(5), pp.241-250; 2009","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MYU"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10790969","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09144935","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yuan, Luyang"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hyodo, Takeo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Yasuhiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Egashira, Makoto"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"SenMat21_241.pdf","filesize":[{"value":"9.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SenMat21_241.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16772/files/SenMat21_241.pdf"},"version_id":"79d07f6b-20cc-4ff2-8efa-996358d05b1d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gas sensor","subitem_subject_scheme":"Other"},{"subitem_subject":"Macropore","subitem_subject_scheme":"Other"},{"subitem_subject":"Mesopore","subitem_subject_scheme":"Other"},{"subitem_subject":"Tin dioxide","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Preparation of Mesoporous and meso-macroporous SnO2 powders and application to H2 gas sensors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preparation of Mesoporous and meso-macroporous SnO2 powders and application to H2 gas sensors"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-22"},"publish_date":"2009-12-22","publish_status":"0","recid":"16772","relation_version_is_last":true,"title":["Preparation of Mesoporous and meso-macroporous SnO2 powders and application to H2 gas sensors"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:37:31.145063+00:00"}
