Ce_xZr_<1−x>O_2 with homogeneous structures were prepared from Ce(NO_3)_3 and ZrO(NO_3)_2 in the presence of formic acid in methanol by rapid heating (500℃/min) to 300℃, while CeO_2–ZrO_2 with domain structures were obtained by slow heating (5.4℃/min). Treatment of mesoporous and spherical ZrO_2 nanoparticles with a Ce(NO_3)_3 solution in supercritical conditions yielded CeO_2-ZrO_2 nanocomposites with core-shell morphologies, while solvents playing a key role in controlling the thickness of the outer shell; methanol produced a very thin outer shell (<1 nm) of cubic CeO_2 and 2-propanol afforded a thick outer shell (100-200 nm) of cubic CeO_2.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.supflu.2014.12.004","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0896-8446","subitem_source_identifier_type":"ISSN"}]},"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":"Pradeep, Ellawala K.
