Abstract Filament‐like Carbon Nanostructures were synthesized by decomposition of acetylene over an alumina supported palladium catalyst prepared by the SMAD method. The structure of carbon products was analyzed by transmission electron microscopy. Between 500 and 700 °C the predominant structures were carbon nanofibers. Between 750 and 800 °C an important mass and volume increase of carbon products was observed. For this temperature range most of the Carbon was in the form of high quality multiwall carbon nanotubes.
