Abstract:
Carbon nanotubes (CNTs) are a form of crystalline carbon with extraordinary properties, making them valuable in a broad range of applications. However, the lack of suitable large-scale manufacturing techniques, which we define as being of the order 10000 tonnes per annum, continues to inhibit their widespread use. Of the three established synthesis methods for CNTs: (i) chemical vapour deposition (CVD), (ii) laser ablation, and (iii) arc discharge, CVD techniques show the greatest promise for economically viable, large-scale synthesis. In particular, the fluidised bed CVD (FBCVD) technique, wh

The production of acetic acid, via the transition metal catalysed carbonylation of methanol, is well established as a major commercial application of homogeneous catalysis. Since the 1960s, when a cobalt-based catalyst was first used industrially by BASF, methanol carbonylation processes have continuously evolved and improved. Notably, Monsanto developed a rhodium/iodide catalyst system, variants of which have been operated by a number of companies. More recently, the journey down group 9 of the periodic table was completed by the commercialisation of an iridium/iodide based catalyst system by
