A recent report detailing a unique preparation procedure for a CHA-type titanosilicate (Ti-CHA) zeolite—in which titanium heteroatoms were incorporated into the zeolite framework by substitution of aluminum—demonstrates excellent physico-chemical properties when compared with conventional aluminosilicate CHA-type zeolites. In this study, the synthesis of Ti-CHA zeolite membranes (Ti-CHA membrane) was investigated. The Ti-CHA membrane was synthesized on an alumina support via a secondary growth method using Ti-CHA zeolite seed crystals. The Ti-CHA membrane properties were studied as a function of seed crystal size. The average particle diameter was observed to reduce from 2.3 μm to 450 nm by increasing the loading of Ti-CHA into the synthesis gel. Regardless of the seed crystal particle size, the presence of CHA-type zeolites on the alumina support was confirmed by x-ray diffraction. UV-Vis demonstrated the incorporation of titanium heteroatoms into the zeolite framework. The results indicated the successful synthesis of the Ti-CHA membrane regardless of the seed crystal particle size. Additionally, the membrane thickness decreased by using the seed crystal. Single gas permeation tests showed that the thinnest Ti-CHA membrane prepared in this study exhibited a relatively high CO2 permeance of 1.5×10−6 mol m−2 s−1 Pa−1, compared with that of previously reported CHA-type zeolite membranes. The influence of moisture on the separation performance of the Ti-CHA membrane was evaluated in the presence of gas mixtures composed of CO2, methane and H2O ranging from 0.1 to 5 vol.%. In the presence of 1 vol.% H2O, the CO2 permeance and selectivity were only marginally reduced as a result of the highly hydrophobic pore structure.","subitem_description_type":"Other"}]},"item_12_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"This work was partially supported by Kansai University Fund for Supporting Young Scholars, 2018.","subitem_description_type":"Other"}]},"item_12_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"34908","nameIdentifierScheme":"WEKO"}],"names":[{"name":"荒木, 貞夫"}]},{"nameIdentifiers":[{"nameIdentifier":"34909","nameIdentifierScheme":"WEKO"}],"names":[{"name":"今坂, 怜史"}]},{"nameIdentifiers":[{"nameIdentifier":"34910","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山本, 秀樹"}]}]},"item_12_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_12_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.micromeso.2019.109798","subitem_relation_type_select":"DOI"}}]},"item_12_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2020.
