摘要：

Au nanoparticles dispersed over a self-organized nanotubular TiO2 matrix can be used as a highly efficient catalyst system for the electrochemical oxygen reduction reaction in aqueous solutions. For the same loading of Au nanoparticles, the nanotubular support provides a manifold increase in the reaction rate in comparison with a flat TiO2 support, or a pure Au sheet electrode.
