Meeting point : Carbon nanotubes (CNTs) are produced by an equimolar reaction between C 2 H 2 and CO 2 (see scheme). CO 2 can be introduced as a gas or a carbonate support of the metal particles. When CaCO 3 is used, the growth of a nanotube stems from the triple‐point junction, which corresponds to the area surrounding the metal support interface where CO 2 , C 2 H 2, and the support meet.
