Single-step synthesis of carbon nanotubes/iron/iron oxide composite films through inert-ambient CVD using ferric acetylacetonate as a precursor

Fe–Fe₃O₄–CNT composite thin film was obtained by single step chemical vapor deposition process using Fe(acac)₃ as the sole precursor. By changing the deposition pressure, the form of carbon deposited could be changed from amorphous to CNTs.
