Solution ^\u003c11\u003eB-NMR revealed the presence of AB after NH_3/N_2H_4 treatment of milled h-BN (BNH_x) although the yield of AB was less than 5%. The conversion mechanism was clarified as B-H bonds on the h-BN surface created by ball-milling under hydrogen pressure have an ability to form AB, which was confirmed by Thermogravimetry-Residual Gas Analysis (TG-RGA) and Infrared (IR) analysis. The reaction routes are also the same as regeneration route of polyborazylene because intermediates of AB such as (B(NH_2)_3 and hydrazine borane were found by solution ^\u003c11\u003eB-NMR after soaking BNH_x in liquid NH_3 and hydrazine, respectively. Because of the fact that all reactions proceed on the h-BN surface and no reaction proceeds when neat h-BN is treated, breaking of B_3N_3 ring structure and then creation of B-H bond is the key issue to increase conversion yield of AB.", "subitem_description_type": "Other"}, {"subitem_description": "論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "en", "subitem_1522300316516": "MDPI"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/47495"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "1996-1073"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "en", "subitem_1522650091861": "Energies"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2020-10-23", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "21", "bibliographicVolumeNumber": "13"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "https://doi.org/10.3390/en13215569"}}, {"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "https://doi.org/10.3390/en13215569"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "energies-13-05569-v2.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2011297/files/energies-13-05569-v2.pdf"}, "version_id": "16abfd4b-0a3c-46d3-b44b-d43f69de796a"}]}, "item_title": "Surface-Controlled Conversion of Ammonia Borane from Boron Nitride", "item_type_id": "15", "owner": "1", "path": ["1642838338003", "1642838406414"], "permalink_uri": "http://hdl.handle.net/20.500.12000/47495", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-12-15"}, "publish_date": "2020-12-15", "publish_status": "0", "recid": "2011297", "relation": {}, "relation_version_is_last": true, "title": ["Surface-Controlled Conversion of Ammonia Borane from Boron Nitride"], "weko_shared_id": -1}
