The variables and methods tested were the mixing ratio of Na2SnO3-3H2O as a tin source and trimethylbenzene in the precursor solution, stirring or ultrasonic treatment after the hydrolysis of the precursor solution, and mechanical grinding of resulting m-SnO2 powders in an agate motor. Among them, ultrasonic treatment immediately after the hydrolysis of Na2SnO 3-3H2O was very effective in reducing agglomerate size and in obtaining a large specific surface area (SSA) of more than 300 m2 g-1, even after calcination at 600°C for 5 h, while grinding in the agate mortar after the calcination led to a decrease in SSA of all m-SnO2 powders. The m-SnO2 sensor fabricated with ultrasonically treated powder showed relatively high H2 sensing properties, probably owing to the small-size agglomerates and large SSA.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Sensors and Materials, 21(5), pp.229-239; 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":"Hario, Naoyuki"}],"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_229.pdf","filesize":[{"value":"9.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SenMat21_229.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16773/files/SenMat21_229.pdf"},"version_id":"a38729c3-2f8f-445e-95b6-d606dba9c88e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Agglomerate","subitem_subject_scheme":"Other"},{"subitem_subject":"H 2 sensor","subitem_subject_scheme":"Other"},{"subitem_subject":"Mesoporous structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Tin dioxide","subitem_subject_scheme":"Other"},{"subitem_subject":"Ultrasonic treatment","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":"Microstructural control of mesoporous SnO2 powders and their H2 sensing properties","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Microstructural control of mesoporous SnO2 powders and their H2 sensing properties"}]},"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":"16773","relation_version_is_last":true,"title":["Microstructural control of mesoporous SnO2 powders and their H2 sensing properties"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:37:30.726611+00:00"}
