title: Nanoparticle and nanorod TiO2 composite photoelectrodes with improved performance.
abstract: A novel nanoparticle-nanorod composite TiO(2) photoelectrode is fabricated. A 3.20% efficiency is achieved by using a 2.1 μm-thick as-prepared photoelectrode, which is about 3 times of that obtained by a nanorod array electrode (1.05%). The results demonstrate that the composite nanostructure can take advantage of both fast electron transport (nanorod) and high surface area (nanoparticle).
