This study analyzes carbon deposition over iron powders and supported particles. The carbon morphology over iron powders was found to vary with the powder size (10-63 μm) and the reaction gas compositions. Gas mixtures containing greater amounts of H2 and less amounts of CO and CH4 produced more well formed ribbons. Over supported iron particles, the filaments were poorly formed tubes, considerably different than the morphology observed over the bulk powders.
