Catalyst influence on the flame synthesis of aligned carbon nanotubes and nanofibers

Since prepared substrates offer an appropriate method for the selective production of uniform arrays of aligned CNTs and CNFs, it is important to illustrate the influence of different catalysts on the resulting nanostructures. This investigation characterizes the activity of three catalysts—iron in alloyed form as stainless steel, nickel, and platinum—on carbon nanostructure formation under identical conditions in an ethylene/air nonpremixed …
