The successful synthesis of carbon nanotubes within a flame environment usi
ng metal nanoparticles supported on TiO2. The nanotube structures reflect t
he metal catalyst particle shape. The name environment, furnishing molecula
r and atomic radical species allows stabilization of chevron, stack-of-card
