The second part of the talk deals with the newly discovered chemical mechanism in the synthesis of Carbon Nanotubes (CNTs). Mixing C2H2 and CO2 in an equimolar proportion (C2H2/CO2 =1) provides outstanding kinetics characteristics of the reaction, leading to a large-scale production of carbon nanotubes free of amorphous carbon. The equimolar C2H2-CO2 reaction allows CNTs growth at temperatures well below 500°C without any arduous pre-activation of the catalyst, on numerous functional materials like oxides, nitrides, carbides or metals. It is an attractive synthesis pathway for the direct integration of CNTs into devices which do not support the traditional high temperature synthesis of CNTs.
