Description
<溶液の調製>
先ず、酢酸亜鉛二水和物0.224g(1mモル)及び2−メチルイミダゾール0.164g(2mモル)をそれぞれ溶媒であるジメチルホルムアミド10mlに完全に溶解させ、さらに2−メチルイミダゾールの溶液に分子性触媒[(CoMeCp)3S2](BF4)2を0.1g加えて溶解させた後に、得られた二つの原料溶液を混合し、液温を25℃に保ったまま攪拌した。なお、ここでMeCpはメチルシクロペンタジエンを意味する。
<噴霧、加熱、回収>
上記懸濁液を2流体ノズルを用いて霧化し、250℃に設定した加熱炉に送り込んだ。この際、キャリアガスとして窒素ガスを用い、ガス流量は3L/minとし、加熱炉における加熱時間が2〜3秒になるよう制御した。
<評価>
上述のようにして得られた粉末について、ブルカーエイエックスエス製新型完全自動多目的X線回折装置D8 ADVANCEでXRD測定を行った結果、[Zn(2MeIM)2]で示される多孔性金属錯体が含まれていることを確認できた。なお、図1にX線回折図を示す。
分子性触媒[(CoMeCp)3S2](BF4)2を除く原料を用いて懸濁液を得た後、分子性触媒[(CoMeCp)3S2](BF4)2を添加して原料溶液を調製した以外は、実施例1と同様にして粉末を得た。この粉末について実施例1と同様、XRD測定、FT−IR測定、CO2の吸着測定を行った結果、粉末は[Zn(2MeIM)2]で示される多孔性金属錯体と[(CoMeCp)3S2](BF4)2との複合触媒であり、CO2に対する吸着能を有するものであった。
機能性材料を[(CoMeCp)3S2](BF4)2からPd粉末に変更し、混合攪拌する時間を30分間にした以外は実施例1と同様にして粉末を得た。この粉末について実施例1と同様、XRD測定、CO2の吸着測定を行った結果、粉末は[Zn(2MeIM)2]で示される多孔性金属錯体とPd粉末との複合触媒であり、CO2に対する吸着能を有するものであった。
