Description
本発明の望ましい一実施形態により、遷移金属MをNiとし、ジメチルグリオキシム(DMG)2分子とNiとから成るキレート錯体Ni−DMGを350℃で加熱して、炭素粒子に担持されたNiナノ粒子を生成した。手順および条件は以下のとおりであった。
〔実施例2〕
本発明の更に望ましい一実施形態により、実施例1のキレート錯体Ni−DMGとアルミナとの混合物を350℃で加熱して、アルミナ粒子に担持されたNiナノ粒子を生成した。手順および条件は以下のとおりであった。
実施例2と同じNi−DMG/アルミナ混合粉末を用い、加熱温度を250〜450℃の範囲で種々に変えて同様の加熱処理を行った。得られた生成物の比表面積の変化を加熱温度に対して図3に示す。
実施例1および実施例2でそれぞれ得られたNiナノ粒子と、従来のバルクNi粒子(比表面積1m2/g未満、粒径数μmオーダー)とについて、0〜30MPaの範囲で圧力を変化させて室温での水素吸蔵量を測定した(測定方法は実施例1、2と同様)。結果を図4にまとめて示す。
