Abstract

Herein, we report a facile method for synthesizing graphitic carbon domains of thin island shapes on the surfaces of titania nanotubes, which were prepared by using hydrothermal and pyrolytic treatments with glucose. The faster decay time of the solar-driven electrons and the lower charge transport resistance on carbon domains as compared to those in the case of bare titania nanotubes serve to increase the solar-to-hydrogen conversion rate.
