Description
図2に示す方法で、グラフェンオキサイド吸着材を製造した。まず、容器に、0.5gのグラファイト粉末を測り取り、2.5gのリン酸水溶液(H3PO4水溶液、濃度:85質量%)、20gの濃硫酸(H2SO4、濃度:97質量%)、2.5gの過マンガン酸カリウム(KMnO4)粉末を加え混合溶液を調製して、35℃で2時間撹拌した。次いで、上記混合溶液に、50mLの水(H2O)を加え、よく撹拌した。その後、上記混合溶液に、1mLの過酸化水素水(H2O2、濃度:10質量%)を加え、25℃で30分間撹拌した。この過程で、グラファイトのグラフェン層を酸化し、表面官能基を生じさせ、さらに酸化したグラフェン層をグラファイトからはく離させることによって層状グラフェンオキサイドを含む溶液を調製した。
得られたグラフェンオキサイド吸着材の軽水及び重水に対する吸着性能を評価した。結果を図3に示す。図3は、グラフェンオキサイド吸着材における、軽水と重水との吸着量を示す吸着等温線である。当該吸着等温線の縦軸は水の吸着量(Water adsorption volume[mmol/g])を示し、横軸は吸着平衡時の水蒸気の圧力(P/P0[-])を示す。図3中、黒塗りの円(実線)は吸着時の軽水の吸着量、白抜きの円(破線)は脱離時の軽水の吸着量、黒塗りの三角形(実線)は吸着時の重水の吸着量、白塗りの三角形(破線)は脱離時の重水の吸着量を示している。
実施例1のGO吸着材の安定性を確認するため、熱重量測定を行った。熱重量測定においては、GO吸着材を静置し、1分ごとにN2ガスを150mL供給するとともに、1分ごとに系の温度を室温から1Kずつ上昇させて行った。実験は3つのサンプルで行った。結果を図5に示す。
実施例1のGO吸着材を80℃で120分間加熱処理して、グラフェンオキサイド吸着材を得た。かかる操作は、実施例1の凍結乾燥に代えて、通常の乾燥操作を行ったものに相当する。得られたグラフェンオキサイド吸着材の軽水及び重水に対する吸着性能を評価した。結果を図4に示す。
以下に示すモディファイド・ハマーズメソッドを用いて、グラフェンオキサイド分散液を調製し、これを加熱乾燥することによってグラフェンオキサイド吸着材を得た。
