Vertically aligned carbon nanotubes (VACNTs) have become one focus in carbon researches.The CNTs in the array form are of almost the same aspect ratio, good orientation and high purity, showing excellent properties.The key of realizing a lot of promising applications and achieving its industrialization is the mass production of CNT arrays at low cost.Here, a lamellar catalyst was obtained by traditional impregnating methods with lamellar structure compounds as carrier.The active catalyst particle can be distributed among the layers.
