摘要：

Graphene-TiO2 nanocomposites synthesized via a solution-based method involving photocatalytic reduction of graphene oxide have been employed as photoanodes. Nearly 90% enhancement in the photocurrent is seen as reduced graphene oxide serves as electron collector and transporter. Additionally, the graphene TiO2 nanocomposite electrodes exhibit significant activity for the complete photocatalytic decomposition of 2,4-dichlorophenoxyacetic acid (2,4-D). Combined with safe, solution-based synthetic practices, the promising photocurrent and photocatalytic degradation rates provide the framework and motivation for the implementation of graphene-TiO2 nanocomposites on larger scales.
