高通量筛选已用于优化碳纳米管生长的催化剂组合物。通过将金属盐溶液印刷到石英基底上形成候选催化剂的微阵列。每种溶液形成一个直径约250 μm的斑点，密度为每平方英寸384个不同的斑点。该溶液由三种组分组成：催化剂前体、底物前体（TEOS）和胶束剂（P85）。将印刷的基底煅烧，然后在甲烷和氢气中反应。使用拉曼光谱和电子显微镜研究了反应的基板。研究了改变三种组分的相对量的效果。分析表明，当金属与硅的比例较高时，生长出竹纳米管，当比例较低时，生长出小直径的纳米管，包括一些单壁管。
High-throughput screening has been used to optimise the catalyst composition for the growth of carbon nanotubes. Microarrays of candidate catalysts were formed by printing metal salt solutions onto quartz substrates. Each solution formed a spot approximately 250 μm in diameter, with a density of 384 different spots per square inch. The solutions consisted of three components: a catalyst precursor, a substrate precursor (TEOS) and a micelle agent (P85). The printed substrates were calcined and then reacted in methane and hydrogen. The reacted substrates were studied using Raman spectroscopy and electron microscopy. The effect of varying the relative amounts of the three components was investigated. Analysis showed that bamboo nanotubes were grown when the metal to silicon ratio was high and small diameter nanotubes, including some single-walled tubes, were grown when the ratio was low.
