However, Fe2O3 still suffers from low PEC efficiency, mainly due to poor electrical conductivity and limited light absorption. This thesis proposes methods for developing hematite photoanodes with improved PEC performance for water splitting. Additional annealing in an argon atmosphere improves the PEC properties by simultaneously increasing donor density and electrical conductivity. Furthermore, 3D macroporous conductive substrates enable higher loading and thinner thickness of the hematite layer, resulting in enhanced PEC efficiency. Additionally, the AEM-PEC system achieves water splitting in pure water without supporting electrolytes, overcoming mass-transport limitations through the synergistic combination of porous photoanodes and solid electrolyte membranes. This low-cost and straightforward device integration of porous hematite photoanodes with AEM exhibits promising potential for advancing sustainable energy production through PEC applications.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第235号"}]},"item_10006_version_type_18":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"デワンガ　オキ　バグス　アプリアンダヌ","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"Dewangga Oky Bagus Apriandanu","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-01-16"}],"filename":"(KKDE1235DA)甲第235号_デワンガ オキ バグス アプリアンダヌ.pdf","filesize":[{"value":"5.3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://kitakyu.repo.nii.ac.jp/record/2000042/files/(KKDE1235DA)甲第235号_デワンガ オキ バグス アプリアンダヌ.pdf"},"version_id":"9140b6c1-cd20-493d-8af3-ec0fc107984f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Anion exchange membrane|Hematite|Titanium doping|Photoanode|Post annealing|PEC water splitting|Porous conductive substrate|Titanium felt|Two-compartment cells|Membrane electrode assembly","subitem_subject_language":"en","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Study on Hematite Photoanodes for Photoelectrochemical Water Splitting","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on Hematite Photoanodes for Photoelectrochemical Water Splitting","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"14","path":["10"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-01-16"},"publish_date":"2024-01-16","publish_status":"0","recid":"2000042","relation_version_is_last":true,"title":["Study on Hematite Photoanodes for Photoelectrochemical Water Splitting"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-01-27T05:22:43.000705+00:00"}
