Description	This work focuses on the synthesis and photocatalytic performance of mesoporous TiO2 films containing embedded gold nanostructures. The TiO2 films were prepared by the EISA (evaporation-induced self-assembly) process and loaded with Au either by impregnation followed by reduction with NaBH4 or by pulsed cathodic electrodeposition. The latter approach represents a considerably easier and faster synthetic method and results in dendritic Au nanostructures as a replica of the pore system. The as-prepared composite films were characterized by scanning and transmission electron microscopy (SEM and TEM), UV-vis spectroscopy and Kr adsorption. Photocatalytic oxidation of NO was chosen as the test reaction for elimination of air pollutants. For mesoporous TiO2 films deposited on an ITO layer, the photonic efficiency is higher than for films prepared on glass, because the pore structures are altered.
