Abstract: Semiconducting type carbon nanotubes are efficiently separated from a mixture of semiconducting and metallic carbon nanotubes in a simple manner, by way of treating the carbon nanotube mixture with an organic solution containing nitronium ions, filtering the resulting mixture to recover remaining solids, and heat-treating the solids.

Abstract: Carbon nanotubes have an R value of at least 1.3, where R is defined as the ratio (ID/IG) of an integral value of D band intensity (ID) to an integral value of G band intensity (IG) in the Raman spectrum. Such carbon nanotubes can be used to form a support catalyst with good catalyst activity because the surface defects on the carbon nanotubes promote improved catalyst distribution in that the support catalyst includes catalyst particles having a small mean particle size and a slight variation in particle size. Such a support catalyst has particularly useful properties when used as a catalyst layer for a fuel cell electrode.
Abstract translation: 碳纳米管具有至少1.3的R值，其中R被定义为D带强度（I）的积分值的比值（I / D / SUB> D ）到拉曼光谱中的G带强度（I> G
）的积分值。 这种碳纳米管可用于形成具有良好催化剂活性的载体催化剂，因为碳纳米管上的表面缺陷促进了催化剂分布的改善，因为载体催化剂包括具有小的平均粒径和微小粒度变化的催化剂颗粒。 当用作燃料电池电极的催化剂层时，这种载体催化剂具有特别有用的特性。 -
