Description
Claims (11)
- 金属ナノ粒子を炭素で被覆する方法において、炭素被覆のような前記粒子の被覆は前記粒子の形成と同時に行われることを特徴とする、金属ナノ粒子を炭素で被覆する方法。
- 水素還元法を用いて生成される粒子を、金属塩化物蒸気が水素と比較的低い温度で反応して金属と塩化水素を形成するとき、生成される塩化水素が粒子の表面から急速に気化するにもかかわらず粒子の成長の速度を実質的に制限するように、金属塩化物の含有量を高くなるようにして生じさせるとともに、
炭化水素が前記水素と混合され、その時に炭化水素が金属塩化物及び粒子と反応して、生成された粒子の表面に炭素を生成することを特徴とする、請求項1に記載の金属ナノ粒子を炭素で被覆する方法。 - 前記生成される粒子の数値濃度は、水素の拡散速度が炭化水素の拡散速度より著しく大きいために、炭素層の生成前に既に非常に大きく、また前記炭素層は気化しないために、前記粒子の成長を塩化水素よりも有効に制限し、これと同時に、前記被覆が前記粒子の生成プロセスと同時に行われることを特徴とする、請求項1又は2に記載の金属ナノ粒子を炭素で被覆する方法。
- 比較的少量の水素しか含有しないエチレンなどの短い炭化水素が、最良の炭素源として作用することを特徴とする、請求項1〜3のいずれかに記載の金属ナノ粒子を炭素で被覆する方法。
- 金属ナノ粒子と塩化水素を形成するために金属塩化物蒸気を水素と反応させる炭素被覆金属ナノ粒子の製造方法において、前記反応に炭化水素を導入し、該炭化水素が、形成される前記金属ナノ粒子と反応して、前記金属ナノ粒子の表面に炭素を形成することを特徴とする、炭素被覆金属ナノ粒子の製造方法。
- 前記反応に導入された前記炭化水素が、前記金属塩化物及び前記金属粒子と反応し、形成される前記金属ナノ粒子の表面に炭素を形成することを特徴とする、請求項5に記載の方法。
- 前記炭化水素は、前記水素と混合されて前記反応に導入されることを特徴とする、請求項5又は6に記載の方法。
- 前記反応に導入される炭化水素は、エチレン、エタン及びアセチレンのうちの少なくとも一つを含むことを特徴とする、請求項5〜7のいずれかに記載の方法。
- 前記反応に導入される炭化水素は、エチレン、エタン又はアセチレンであることを特徴とする、請求項5〜7のいずれかに記載の方法。
- 前記金属ナノ粒子の表面に形成される前記炭素の少なくとも一部分は、グラフェンであることを特徴とする、請求項5〜9のいずれかに記載の方法。
- 少なくともグラフェン層1〜2層分の厚さの被覆が、前記金属ナノ粒子の表面上の炭素から形成されることを特徴とする、請求項5〜10のいずれかに記載の方法。
