Synthesis of graphenes on Ni foils by chemical vapor deposition of alcohol with IR-lamp heating

We report the synthesis of single-layer graphenes on polycrystalline Ni foils by alcohol-based chemical vapor deposition (CVD) with IR-lamp heating. Heating with an IR lamp allows fast cooling and a reduction in the overall CVD time because of the rapid thermal processes in the heating and cooling stages. Spatially resolved Raman spectroscopy shows that single-layer graphenes are synthesized by CVD of alcohol with IR-lamp heating. The effects of the reaction temperature and alcohol type on the number of layers and graphene quality are investigated.

► Graphene growth by CVD using alcohol with IR lamp heating.
► The obtained graphenes were characterized by spatially resolved Raman spectroscopy.
► Single-layer graphenes were synthesized at 1000 °C.
► Increasing the growth temperature improves the graphene quality.
