Graphene is a flat monolayer of carbon atoms arranged in a honeycomb lattice.Graphene has many outstanding properties such as high electron mobility,superb strength,transparency and great flexibility.These exotic properties make graphene a promising candidate for solar cell,fuel cell,battery,supercapacitor and so on.In this report,we have studied the effect of acetic acid pre-treatment on the growth temperature of graphene on copper by thermal chemical vapor deposition(CVD).In case of graphene growth without acetic acid pre-treatment,the high temperature of 1000 °C is needed for the growth of graphene by CVD.In contrast,the growth temperature can be decreased to 800 °C for graphene growth with acetic acid pre-treatment.We found that acetic acid pre-treatment can eliminate copper oxide from the sample surface resulting in the growth temperature of graphene decreases.
