In this study we present the plasmonic effect enhanced photocurrent in gold (Au) decorated on nanostructured TiO 2 films (Au@TiO 2 ). The Au@TiO 2 electrodes were successfully prepared by means of vacuum evaporation, followed by thermal annealing. It was found that the average size of Au nanoparticl...
