Composite materials consisting of ceramic monoliths and carbon nanotubes (CNTs) have been synthesised by chemical vapour deposition on the walls of a cordierite monolith in a single step. The method proposed here avoids the costly pre-treatment steps previously reported in literature for CNT growth onto ceramic monoliths. It is also capable of achieving controlled CNT layer thicknesses of over 150 μm, compared to the 4 m previously reported in literature (Garcia-Bordeje et al.) The new method produces an array of aligned carbon nanotubes on the monolith surface, with varying thickness depending on synthesis conditions (Figure 1). Uniform CNT growth on monoliths up to 12 cm long has been obtained, showing that this process can be scaled up for industrial level catalysis. This new process improves the sustainability, economic viability, and overall properties of the composite material. The composite material provides the means for carbon nanotubes to be used as a catalyst support in a number of chemical reactions.
