A large-area smooth graphene film on a TiO2 nanotube array via a one-step electrochemical process†
Abstract
A large-area smooth graphene film on a TiO2 nanotube array was directly fabricated using a simple, green and low-cost electrochemical process. The controllable formation mechanism of the graphene film is demonstrated in detail. The enhanced photoelectric and photocatalytic properties of the composite film imply great potential applications in various fields.
