Abstract

We report the controllable electrophoretic fabrication of highly robust, efficient, and benign photoelectrocatalysts based on graphene-quantum-dot sensitized TiO2 nanotube arrays. Their catalytic activities under visible-light irradiation remain steady for continuous cycles (400 min) with a negligible decrease, whereas CdS and CdSe sensitized TiO2 nanotube arrays show a high cycling instability due to serious photooxidization.
