The coupled metal sulfide-TiO2 systems possess the following characteristics: (I) a large amount of metal sulfides can be directly formed on TiO_2 during a fairly short period with excellent reproducibility, (II) the band energies of metal sulfides QDs are widely tunable by irradiation time or surface modifier concentration, (III) metal sulfide QDs can be deposited on not only the external surfaces but also the inner ones of mesoporous TiO_2 nanocrystalline films without pore-blocking, (IV) the simple solution-based technique at low temperature enables the low-cost production, (V) this technique has a wide possibility for coupling TiO_2 and narrow gap metal sulfides suitable for the applications to the solar energy conversion. These unique features produce the excellent performances of the resulting heteronanojunaction systems as photocatalysts and the photoanodes for QD-SSC and QD-SPEC cells for hydrogen production from water.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(B);  研究期間：2008～2010;   課題番号：20350097;   研究分野：化学;   科研費の分科・細目：材料化学・無機工業材料","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/60298990"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/40128690"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/80356344"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/60340759"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"TADA, HIROAKI"},{"subitem_text_language":"en","subitem_text_value":"KOBAYASHI, HISAYOSHI"},{"subitem_text_language":"en","subitem_text_value":"AKITA, TOMOKI"},{"subitem_text_language":"en","subitem_text_value":"MATSUI, HIDEO"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"},{"subitem_text_value":"京都工芸繊維大学工芸科学研究科; 教授"},{"subitem_text_value":"（独）産業技術総合研究所; 主任研究員"},{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_version_type_12":{"attribute_name":"版","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":"多田,  弘明"},{"creatorName":"タダ, ヒロアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"小林,  久芳"},{"creatorName":"コバヤシ, ヒサヨシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"秋田,  知樹"},{"creatorName":"アキタ, トモキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松井,  英雄"},{"creatorName":"マツイ, ヒデオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_20350097seika.pdf","filesize":[{"value":"179.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_20350097seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3177/files/KAKEN_20350097seika.pdf"},"version_id":"306b307d-b782-450a-bf00-691e546fd119"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"光触媒","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"光析出法を用いた硫化物半導体－酸化物半導体ダイレクトナノカップリングに関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"光析出法を用いた硫化物半導体－酸化物半導体ダイレクトナノカップリングに関する研究"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3177","relation_version_is_last":true,"title":["光析出法を用いた硫化物半導体－酸化物半導体ダイレクトナノカップリングに関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:44:00.982816+00:00"}
