Hipco carbon nanotube
WebbIn 1999 Richard E. Smalley and his co-workers developed a high pressure carbon monoxide method called HiPco for the synthesis of carbon nanotubes [6]. In this process in the continuous-flow gas phase carbon monoxide acts as a feedstock and iron carbon monoxide Fe(CO)5 as a catalyst. With the HiPco method the WebbA detailed kinetic model of the HiPco process that includes of the precursor, decomposition metal cluster formation and growth, and carbon nanotube growth was developed in …
