Cobalt-filled apoferritin (Co-ferritin) was, for the first time, used as a wet catalyst for the synthesis of single-walled carbon nanotubes (SWNTs) with narrow diameter distribution. Co-ferritins were spin-coated and converted to cobalt nanoparticles by calcination. Using chemical vapor deposition, suspended networks of SWNTs were formed on pillar-structured substrates. The suspended SWNTs show narrow tube diameter distribution with a relatively good graphite structure. By virtue of the low diffusion coefficient of cobalt, Co-ferritin might be more useful for narrow diameter SWNTs growth than ferritins, which encase iron particles.
首次将填充钴的脱铁铁蛋白（钴铁蛋白）用作湿催化剂，用于合成具有窄直径分布的单壁碳纳米管（SWNTs）。将钴铁蛋白旋涂并通过煅烧转化为钴纳米颗粒。使用化学气相沉积法，在柱状结构基板上形成了SWNTs的悬浮网络。悬浮的SWNTs显示出窄的管径分布以及相对良好的石墨结构。由于钴的扩散系数低，与包裹铁颗粒的铁蛋白相比，钴铁蛋白可能更有利于窄直径SWNTs的生长。
