开发了一种简单而通用的发现二元金属纳米颗粒催化剂的组合方法。在该方法中，通过在光刻沉积期间简单地在衬底上方设置具有狭缝的掩模，可以在宽范围内独立地筛选组分金属的标称厚度。使用这种方法，我们在SiO2/Si晶片上制备了具有Mo（0.2- 4 nm）和Co（0.2- 8 nm）厚度分布的催化剂库，并发现了通过醇催化化学气相沉积生长垂直排列的单壁碳纳米管的活性催化剂。
A simple yet versatile combinatorial method to discover binary metal nanoparticle catalysts was developed. In this method, the nominal thickness of component metals can be independently screened for a wide range by simply setting a mask with a slit above a substrate during sputter-deposition. Using this method, we prepared a catalyst library with Mo (0.2–4nm) and Co (0.2–8nm) thickness profiles on a SiO2/Si wafer and discovered active catalysts that grow vertically aligned single-walled carbon nanotubes by alcohol catalytic chemical vapor deposition.
