ポリプロピレン製ビーカー中に828gの蒸留水を装入し、そして撹拌しながら6gの臭化ヘキサデシルトリメチルアンモニウム(CTAB、98%、Sigma Aldrich社)を添加した。この混合物に、2876gの工業用エタノール(96%)を加え、そして澄明な溶液が得られるまで更に撹拌した。次いで、144gのアンモニア溶液(25重量%)を撹拌しながら添加し、そして1時間にわたり更に撹拌した。その後に、20gのテトラエチルオルトシリケート(TEOS、98%、Alfar Aesar社)を添加し、そして得られた混合物を2時間にわたり更に撹拌した。引き続き、生成したSiO2粒子を10000回転/分での遠心分離によって合成混合物から分離し、そして蒸留水で3回洗浄した。最後に、精製されたSiO2粒子を75℃で一晩空気乾燥させ、次に550℃で空気雰囲気において焼成した。
本発明によるゼオライト系ナノ粒子の合成のための出発物としての多孔性Al2O3−SiO2粒子は、Ahmedらによる方法(Ahmed et. al., Industrial & Engineering Chemistry Research, 49 (2010) 602)に変更を加えて製造した。一般的な手法では、先ず4gのポリビニルアルコール(PVA、Mw31k〜50k、98重量%、Sigma-Aldrich社製)をガラスビーカー中で105gの脱イオン水中に80℃で溶かした。約20分〜30分後に、そのPVA溶液に0.12gのアルミン酸ナトリウム溶液(53重量%のAl2O3及び43重量%のNa2O、Chemiewerk Bad Koestritz GmbH社)を80℃で撹拌しながら添加した。それにより生成された混合物を、アルミン酸ナトリウムが完全に溶けるまで更に撹拌した。次いで、その溶液を室温に冷やし、ガラス製の500ml容の撹拌反応器中に移した。引き続き、その冷えた混合物中に1.61gのCTAB及び101gのエタノールを撹拌しながら添加し、そして40℃に加熱した。最後に、7.2gのTEOSを添加し、そして1 TEOS:0.006 Al2O3:2.9 NH3:0.12 CTAB:162 H2O:58 エタノール:0.003 PVAのモル組成を有する得られた合成混合物を40℃で約40時間にわたり更に撹拌した。生成されたSiO2粒子を10000回転/分での遠心分離によって合成混合物から分離し、そして脱イオン水で3回洗浄した。最後に、精製されたAl2O3−SiO2粒子を75℃で一晩にわたり空気乾燥させ、次に550℃で空気雰囲気において焼成した。
1gのSiO2粒子(実施例2)を、テフロン(登録商標)容器中で1.25gの水酸化テトラプロピルアンモニウム溶液(TPAOH、40重量%、Clariant社)と混合し、そして5gの脱イオン水を添加し、更に室温で16時間にわたり撹拌した。次いで、得られた懸濁液を65℃で炉内において6時間にわたり乾燥させた。上記メソ細孔中のTPAOHの負荷度を測定するために、乾燥された粉体を熱重量分析(TGA)により分析した。そこから、約25重量%の有機化合物(有機テンプレート)の割合が導き出され、これは、SiO2粒子の全メソ細孔容積の約83容積%に相当する。さらに、減量−温度図(TGAプロファイル)から、上記有機テンプレート(TPAOH)の大部分がメソ細孔中に存在することが実証され得た。引き続き、乾燥された粉体を細かくすり潰し、それを4つの磁器皿に移し、これらを次に23mL容のテフロン(登録商標)容器中に、図2に示されているように導入した。各テフロン(登録商標)インサート中には、8gの水が存在していた。その際に、水がTPAOH−SiO2粒子と接触しないよう注意した。引き続き、全てのテフロン(登録商標)容器を4つのステンレス鋼製オートクレーブに移し、そして密閉した。最後に、該オートクレーブを110℃で12時間にわたり加熱した。その時間が経過した後に、全てのオートクレーブを室温へと冷やした。その中に含まれる固体を、合成混合物の10000回転/分での遠心分離により分離し、蒸留水で3回洗浄し、75℃で一晩にわたり乾燥させ、引き続き特性評価した。
