In this study, the electrodeposition behavior of the extracted Pt(IV) complex in a phosphonium-based ionic liquid (IL) was investigated by using an electrochemical quartz crystal microbalance (EQCM). The charge transfer reaction Pt(IV) + 2e^− → Pt(II) was observed at −0.53 V. The significant increase in the mass change (Δm) and the apparent molar mass (Mapp) of 193.7, as evaluated by the EQCM, confirmed that the electrodeposition reaction Pt(II) + 2e^− → Pt(0) proceeded at −1.65 V in this system. Moreover, consecutive solvent extraction and electrodeposition of Pt metal in Alamine336/IL system were performed at 10 cycles. High extraction percentage (E > 95.1%) and good current efficiency (ε > 85.8%) were maintained in the first to sixth cycles. The XPS Pt-4f_(7/2) spectrum confirmed that all the electrodeposits were in the metallic state.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Science"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1149/1945-7111/ac120d","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1149/1945-7111/ac120d"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1149/1945-7111/ac120d","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00697016","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"19457111","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Nuclear Science and Engineering Directorate, Japan Atomic Energy Agency"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Matsumiya, Masahiko"}],"nameIdentifiers":[{"nameIdentifier":"34887","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00370057","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00370057"}]},{"creatorNames":[{"creatorName":"Tsuchida  Yusuke"}],"nameIdentifiers":[{"nameIdentifier":"40664","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kinoshita  Ryoma"}],"nameIdentifiers":[{"nameIdentifier":"40665","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki  Yuji"}],"nameIdentifiers":[{"nameIdentifier":"40666","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20354839","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20354839"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-07-16"}],"displaytype":"detail","filename":"manuscript_JES(Pt)_r2.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"manuscript_JES(Pt)_r2.pdf","url":"https://ynu.repo.nii.ac.jp/record/11491/files/manuscript_JES(Pt)_r2.pdf"},"version_id":"236e1fce-d09a-4af8-9522-b750636db952"}]},"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":"Electrodeposition Behavior of Extracted Platinum Complex in Phosphonium-Based Ionic Liquids Evaluated by Electrochemical Quartz Crystal Microbalance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Electrodeposition Behavior of Extracted Platinum Complex in Phosphonium-Based Ionic Liquids Evaluated by Electrochemical Quartz Crystal Microbalance"}]},"item_type_id":"2","owner":"3","path":["501"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-12-21"},"publish_date":"2021-12-21","publish_status":"0","recid":"11491","relation_version_is_last":true,"title":["Electrodeposition Behavior of Extracted Platinum Complex in Phosphonium-Based Ionic Liquids Evaluated by Electrochemical Quartz Crystal Microbalance"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T17:54:39.270908+00:00"}
