Description
カーボンナノチューブは、シリコンウエハまたはガラスなどの基板上に堆積された金属触媒を使用して、炭素リッチガス流中にて化学蒸着を含むいくつかの方法で調製できる。通常、触媒の密度が低いため、カーボンナノチューブは基板の表面に沿って成長する。カーボンナノチューブの合成のための触媒組成物が報告されている。特許文献1を参照されたい。しかしながら、ナノチューブの長さとカーボンナノチューブの整列は、基板全体にわたり大幅に異なる場合がある。
剥離した層状鉱物106を金属イオン114とともに含浸することは、剥離した層状鉱物106を金属イオン水溶液に浸漬110して金属イオン含浸層状鉱物112を生成することにより達成することができる。金属イオン水溶液は、鉄、ニッケル、コバルトの金属塩を含むことができ、それぞれの相対モル比を調整することができる。例示的な金属塩は、限定されるものではないが、硝酸鉄(II)、硝酸鉄(III)、塩化鉄(II)、塩化鉄(III)、臭化鉄(II)、臭化鉄(III)、フッ化鉄(II)、フッ化鉄(III)、硫酸鉄(II)、硫酸鉄(III)、硝酸コバルト(II)、塩化コバルト(II)、臭化コバルト(II)、フッ化コバルト(II)、硫酸コバルト(II)、硫酸コバルト(II)、硝酸ニッケル(II)、塩化ニッケル(II)、臭化ニッケル(II)、フッ化ニッケル(II)、硫酸ニッケル(II)、硫酸ニッケル(II)など、およびそれらの組み合わせを含み得る。
成長122中の反応温度は、約650℃~約750℃の範囲であり得る。
