This work reports the photodeposition of Ag nanoparticles onto mesoporous TiO2 (m-TiO2) pre-formed by the evaporation-induced self-assembly method. Photoanodes of Ag/m-TiO2 assembled by electrophoretic disclose a superior photoelectrochemical (PEC) performance for water oxidation reaction related to m-TiO2. The photoanodes physicochemical investigations witness the even arrangement of m-TiO2 nanospheres particles over the substrates. The PEC study displays a steady photocurrent density of 1 mAcm(-2) at -1.0 V vs SCE was attained for Ag/m-TiO2 photoanodes in visible light illumination and it is nearly twofold enhancements in comparison with m-TiO2 photoanodes. The observed superior PEC nature was attributed to the reduced band-gap energy and charge recombination that caused from the incorporation of plasmonic photodeposited Ag nanoparticles on m-TiO2 nanospheres photoanodes.
