Description
以下、本発明の好適な一実施形態について詳細に説明する。本実施形態に係る水素吸蔵材は、多孔性炭素材を備える。多孔性炭素材の表面には、含酸素官能基が形成され、かつLiが結合している。特に、含酸素官能基が多孔性炭素材のミクロ孔の内壁表面に形成され、かつLiが多孔性炭素材のミクロ孔の内壁表面に結合していることが好ましい。これにより、水素吸蔵能が著しく向上する。
以下では、KOHで賦活されたコークスを多孔性炭素材に用いる水素吸蔵材の製造方法を説明する。
石油コークスに対して、2倍量(質量基準)のKOHを混合し、750℃の窒素ガス雰囲気中における1時間の加熱処理を施すことにより、賦活物を得た。
比較例1と同様の方法で、賦活されたコークスを形成した。このコークスを120℃で4時間真空乾燥した。乾燥後のコークスとLiOH100mgと水30mLとを混合して得た溶液を4時間攪拌して、コークスとLiOHとを反応させた。反応終了後、この溶液を吸引濾過して固体を濾取して、その固体を純水で5回洗浄した。洗浄後の固体を100℃で4時間真空乾燥して、実施例1の水素吸蔵材を得た。
比較例2の水素吸蔵材として、賦活されたコークスを準備した。比較例1と同様の逆滴定の結果、比較例2のコークスの表面には、キノン基、ヒドロキシル基、ラクトン性カルボキシル基及びカルボキシル基が形成されていることが確認された。
比較例2と同様の賦活されたコークスを120℃で4時間真空乾燥した。乾燥後のコークスとLiOH100mgと水30mLとを混合して得た溶液を4時間攪拌して、コークスとLiOHとを反応させた。反応終了後、この溶液を吸引濾過して固体を濾取して、その固体を純水で5回洗浄した。洗浄後の固体を100℃で4時間真空乾燥して、実施例2の水素吸蔵材を得た。
ICP発光分析によって、実施例1の水素吸蔵材に含まれる元素の含有量を求めた。また、実施例1と同様に、実施例2、比較例1及び2の各水素吸蔵材を分析した。元素分析の結果を表3に示す。K,Liの分析には、分析装置として、島津製作所製のICPS−8100を用いた。C,H,Nの分析には、分析装置として、elementar社製のvario EL IIIを用いた。Oの分析には、分析装置として、CE instruments社のEA1110を用いた。表3に示す各元素の含有量の単位は、各水素吸蔵材1gあたりのモル数を表す。
実施例1の水素吸蔵材の入ったサンプル管部分を303Kの水槽に浸した状態で、実施例1の水素吸蔵材の水素吸蔵量を測定した。水素吸蔵量の測定には、(株)レスカ製の水素吸蔵量測定装置を用いた。303Kにおける水素の平衡圧と実施例1の水素吸蔵量との関係を図3に示す。また、温度が303Kであり、水素の平衡圧が10MPaであるときの実施例1の水素吸蔵量を表4に示す。
