Description
A.試料の合成
(1) 炭素化前試料調製
カルボキシメチルセルロースナトリウム(日本製紙株式会社製、エーテル化度0.7、平均分子量250000)と鉄ミョウバン(関東化学株式会社製試薬)を、カルボキシメチルセルロースナトリウムに対する鉄ミョウバンの質量比が0wt%、5wt%、15wt%、100wt%となるように水に溶解させ、次にカルボキシメチルセルロースナトリウムを2wt%となるように加えて撹拌し、その後60℃の乾燥機で24時間程度乾燥させたものを炭素化前試料とした。
(1)で調製した試料をアルミナボートに秤量し、電気管状炉を用いて窒素雰囲気下、昇温速度10℃/minで700℃または900℃まで加熱し、1時間保持することで炭素化を行った。炭素化後の試料は試料名に炭素化温度をC700のように添字する。
(1) 粉末X線回折
炭素体および生成金属塩の結晶性および同定を行うために、粉末X線回折測定(X線回折装置RINT2100ultima+、株式会社リガク製を使用)を行った。炭素体は測定前に乳鉢で粉砕し、CuKα線、スキャンスピード4deg./min、スキャン間隔0.02deg.、測定範囲2〜80deg.の条件で測定を行った。
炭素体の磁性の評価を行うために、VSM法(PPMS DynaCool-9YA、日本カンタム・デザイン株式会社製を使用)を用いた。5 K、100 K、300 Kの温度条件下、ZFCで磁化曲線の測定を行った。また、磁性の温度依存を測定するために、0.01 T、0.1 T、1 T、3 Tの磁場でZFC-FC測定を行った。
炭素体の細孔特性を評価するために、-196℃における窒素吸着測定(BELSORP mini、日本ベル株式会社製を使用)を行った。炭素体は測定前に乳鉢で粉砕し、アルゴン雰囲気下、300℃で24時間吸着前処理を行った。測定により得られた窒素吸着等温線からBET法,αs法にて比表面積、細孔容積を求めた。
炭素体の吸着能力評価の一つとして、VOC吸着実験を行った。炭素体0.1 gに調製濃度500 ppbの各VOC溶液10 mLを添加し、環境庁告示第46号に準じた4時間振とう後に分析を行った。VOCであるジクロロメタン、1,1,1-トリクロロエタン、四塩化炭素、トリクロロエチレンを用いて、それぞれ各単成分の吸着実験を行った。
鉄ミョウバン(関東化学株式会社製試薬)をカルボキシメチルセルロースナトリウム(日本製紙株式会社製、エーテル化度0.7、平均分子量250000)に対する濃度比で5 wt%、15 wt%となるように水に溶解させ、次にカルボキシメチルセルロースナトリウムを2 wt%となるように加えて撹拌しゲルを作製した。
Claims (2)
- カルボキシメチルセルロースナトリウムと前記カルボキシメチルセルロースナトリウムに対して5〜15質量%の鉄化合物を水に溶解させて混合し、ゲルが生成された後に、700〜900℃の熱を加えて炭素化させることで、鉄粒子が均等に分散されるようにして鉄粒子−多孔質炭素複合体を製造することを特徴とする鉄粒子−多孔質炭素複合体の製造方法。
- 請求項1記載の鉄粒子−多孔質炭素複合体の製造方法において、前記鉄化合物が3価の鉄イオンを含む鉄ミョウバンであることを特徴とする鉄粒子−多孔質炭素複合体の製造方法。
