Synthesis and investigation of photocatalytic and CO2 photoreductive properties of Ag/TiO2 nanowires

Silver nanoparticles with the diameter of 5 – 10 nm were successfully deposited on TiO2 nanowires by a facile and low-cost photoreduction method in alkaline solution under UV irradiation. The mutual coordination between light irradiation and NH4OH reduction gives rise to the formation and decoration of the Ag nanoparticles on the surface of TiO2 nanowires.
