We report synergetic effect enhanced photoelectrocatalysis, in which Fe3+ and Br− are used as the acceptors of photogenerated charges on TiO2 nanoparticles. The kinetic rate of interfacial charge transfer is promoted from (4.0 ± 0.5) × 10−4 cm s−1 (TiO2/(O2, Br−)) to (1.5 ± 0.5) × 10−3 cm s−1 (TiO2/(Fe3+, Br−)). The synergetic effect provides a valuable approach to the design of photoelectrocatalytic systems.
